What’s the difference between an all-in-one and a desktop?
A desktop computer typically consists of a tower that houses things like the processor, memory, and other internal components, offering more options for customisation or upgrades. To use it, you’ll need to purchase separate peripherals such as a monitor, keyboard, and mouse. Whereas an all-in-one computer integrates all these components into a single unit, resulting in a sleeker, space-saving design.
What type of desktop computer is best?
At Harvey Norman, we offer a diverse range of desktop computers and all-in-one systems that cater to every computing need. Explore our selection to find the right one for you:
Desktop Computers – Also called a desktop tower, they present incredible powerful processing power with parts that can be easily upgraded or replaced. This is essential for those who want to build their own computer, as it allows you to hand-select each component to suit your performance needs and user requirements.
All-In-One Computers – If you want something that combines the compact design of a laptop with the processing prowess of a desktop, an all-in-one PC offers the ultimate convenience. Showcasing a slim, user-friendly design, they are easy to set up and come built with everything you need – keeping wires, power units, and external devices to a minimum.
Mini PCs – Just as capable as a desktop, mini-PCs are a pint-sized powerhouse that keeps a low profile, perfect if you’re short on desk space or want something small enough to transfer in a backpack when you’re working between home and the office.
Gaming PCs – If games are your thing, invest in a desktop that is built for gaming. With powerful processors, high-performance GPUs, faster load times, and advanced cooling, they have everything you need to get your game on.
As well as desktop computers, Harvey Norman has a huge range of laptops and 2 in 1s for those on-the-go, including the new AI-powered Copilot+ PCs.
What should I look for when buying a desktop computer?
When choosing a new desktop computer or all-in-one PC, it all comes down to the intended use and your budget. First and foremost, consider how you’ll be using your PC – is it for work, content creation, gaming, or general use? This will help you select the right specifications for your requirements, such as processing power, RAM, graphics capabilities, and storage capacity. You’ll also need to factor in your space, as desktop computers come in various sizes. Whatever your needs or budget, you’ll find the right desktop computer at Nerdcore PC Systems.

The graphics card (GPU) is one of the most important components for gaming on a PC. It's what handles all the pretty eye candy on-screen, working with the CPU, RAM and display to offer an immersive gaming experience. The issue — especially for new system builders and new PC gamers — is that there is a wide collection of GPUs available. So which is right for you? We've got some recommendations on your new custom nerdcore pc.
Products used in your latest nerdcore Gaming pc
1080p gaming: GTX Series
1440p gaming: RTX Series
4K gaming: RTX Series
Working out what GPU your nerdcore pc needs
Figuring out just how much you should spend depends on a number of factors:
Screen resolution: Will you be playing games at 1080p or 4K?
Budget: How much do you plan on spending on a GPU? The more the better.
Future proofing: Do you have plans to upgrade your 1080p monitor at a later date?
System specifications: All the good stuff currently installed inside your PC chassis.
The last point can be covered quickly by recommending an Intel Core i3 and Core i5, or AMD Ryzen 7 and 9, processors for 1080p and 1440p gaming. Intel Core i5 and i7, i9 or AMD Ryzen 5 - 7 and 9 processors are best suited for more advanced 1440p gaming and 4K. The amount of RAM you should have in 2024 is at least 64 or 128 GB, and preferably 16GB. 32GB should be considered for streaming and other intensive tasks.
As for budget, you really should fork out for the most expensive GPU you can afford. It's better to spend more now than having to upgrade again soon. It's worth reminding potential GPU buyers that prices for graphics cards are still rather high right now, so it's worth shopping around.
Which resolution is best for you?
1080p, 1440p and 4K are all different resolutions with each subsequent one requiring considerably more graphics processing power to handle millions of additional pixels on a display. Deciding on which resolution to play games at can be a little confusing in of itself, so this guide will walk you through each one and clear up all the jargon.

Recommended GPUs for 1080p gaming
Picking up a monitor with a resolution of 1080p is still a popular option for many gamers. The best part about this amount of pixels on a display is it doesn't require much processing power. It's easy to get away with a less powerful processor and more affordable GPU. Still, if you wish to enjoy a more fluid visual experience and take advantage of a monitor with a higher refresh rate, more power will make all the difference.
The GTX 4060Ti is NVIDIA's most affordable RTX-class desktop GPU, but don't allow the pricing to fool you into assuming it's not powerful enough for gaming in 2024. You'll be able to enjoy most titles at medium settings for visual quality. Stepping up to the GTX 4090 Ti takes everything up a notch.
Prices currently range from $400 to $4000.00
Recommended GPUs for 4K gaming
These top picks for best graphics card are overkill for both 1080p and 1440p, but can be used with the latter when taking into account mods and really demanding titles at maximum settings. What these expensive components offer is the capability to play games at 4K. The RTX 4080 from NVIDIA is the entry point at this resolution, and the 4080 Ti offers even more power.
Depending on what kind of screen you hook up to the PC, as well as what connections are available, you may be locked to 30 frames per second (FPS) at 4K, which isn't too good. It's worth making sure all the equipment you'll be buying to make sure you get the best experience for the money.
For top-tier 4K gaming, the Nvidia GeForce RTX 5090 is the ultimate choice, while the RTX 5080 and AMD Radeon RX 9070 XT offer excellent performance as high-end alternatives, often providing great value and smooth frame rates at 4K. For a strong midrange 4K option, the Nvidia RTX 5070 Ti is highly recommended for its 16GB VRAM and solid performance, with the AMD Radeon RX 9070 XT also a strong contender
Top-Tier (Uncompromised 4K)
NVIDIA GeForce RTX 5090: The absolute best, offering flawless ray tracing and maximum futureproofing with 32GB GDDR7 VRAM
High-End (Excellent Performance & Value)
NVIDIA GeForce RTX 5080: A strong performer for 4K, providing near-top-tier experience at a lower (but still high) cost.
AMD Radeon RX 9070 XT: A fantastic overall value AMD card for 4K, delivering smooth gameplay and strong ray tracing with 16GB GDDR6 VRAM
Midrange (Great 4K Entry & Value)
NVIDIA GeForce RTX 5070 Ti: A fantastic price-to-performance option for 4K, featuring 16GB VRAM and often hitting over 80 FPS in demanding games.
AMD Radeon RX 9070: A capable midrange AMD card for 4K, though it may show limitations in very demanding titles compared to higher-end options.
Budget-Friendly 4K (With Compromises)
AMD Radeon RX 9060 XT (16GB): An affordable entry point that uses its 16GB VRAM well in 4K, but performance will be limited in new AAA games.
NVIDIA GeForce RTX 4060 (or newer 5060): Can handle 4K for older or less demanding games, but you'll heavily rely on DLSS and may need lower settings for smoother frame rates in modern titles
Frequently asked questions
Gaming PC
• Prioritise the GPU: For gaming, the Graphics Card is your most important component. Aim to spend roughly 30-50% of your budget here.
• Enable XMP/EXPO: Once built, you must enter the BIOS to enable XMP (Intel) or EXPO (AMD) profiles, or your RAM will run at slower "default" speeds rather than its advertised performance.
• Dual-Channel RAM: If you have two sticks of RAM and four slots, place them in slots 2 and 4 (check your manual) to enable dual-channel mode for a significant FPS boost
If you're looking for inspiration or a "Ready-to-Run" baseline, here are some high-performance configurations currently available
For a visual walkthrough, these resources are highly recommended for 2026 builders:
• Video Tutorials: YouTube guides like How to Build a PC - 2026 Edition (/post/build-your-dream-gaming-pc-in-australia-gaming-pc-nerdcore-pc)provide detailed visual steps.
• Detailed eBooks: Specialized guides like
How to Build a Gaming PC
(/post/build-your-dream-gaming-pc-in-australia) offer comprehensive checklists for every stage of the process.
Do you have a specific budget in mind, or would you like to see a parts list tailored for a certain game?
• The "Plastic Peel": Forgetting to remove the protective plastic sticker from the bottom of your CPU cooler before installation will cause immediate overheating.
• I/O Shield: If your motherboard doesn't have an integrated one, you must install the metal I/O shield into the case before mounting the motherboard.
• Plug into the GPU: Always plug your monitor's HDMI or DisplayPort cable into the Graphics Card, not the motherboard, to ensure you're actually using your GPU.
• Motherboard Standoffs: Ensure you use standoffs to elevate the motherboard off the metal case frame to prevent a short circuit.
• PSU Cables: Never mix modular power supply cables from different models; they are often pinned differently and can fry your components.
3. How do I get the best performance for my budget?
• Prioritise the GPU: For gaming, the Graphics Card is your most important component. Aim to spend roughly 30-50% of your budget here.
• Enable XMP/EXPO: Once built, you must enter the BIOS to enable XMP (Intel) or EXPO (AMD) profiles, or your RAM will run at slower "default" speeds rather than its advertised performance.
• Dual-Channel RAM: If you have two sticks of RAM and four slots, place them in slots 2 and 4 (check your manual) to enable dual-channel mode for a significant FPS boost.
Your monitor dictates your GPU choice. Are you aiming for 1080p high-refresh, 1440p (the current "sweet spot"), or 4K ultra?
ypically, 30-50% of your total budget should be allocated to the graphics card, as it has the most direct impact on gaming performance.
For 2026 builds, consider if your motherboard socket (like AMD’s AM5) will support future CPU generations so you don't have to replace the whole board later.
If you plan to stream, edit 4K video, or run heavy multitasking, you may need a higher core-count CPU and 32GB+ of RAM rather than the standard 16GB.
Budget CPUs often include "stock" coolers, but high-end chips require separate air or liquid (AIO) cooling solutions.
Don't just look at wattage; check for an 80 Plus Gold rating or better. Using a low-quality PSU can risk damaging every other part in your system.
High-end GPUs in 2026 are often massive (up to 350mm+). Always check the case specifications for "Max GPU Length" and "CPU Cooler Height."
If you can't run a hardwired ethernet cable, ensure your motherboard specifically lists Wi-Fi 6 or 7 support.
After building, have you entered the BIOS to ensure your RAM is actually running at its advertised speed?
Ensure your CPU is powerful enough to "feed" your GPU; pairing a budget CPU with a flagship GPU will waste the card's potential.
You’ll need a magnetic Phillips head screwdriver, a clean workspace, and ideally an anti-static wrist strap.
For 1440p or 4K gaming, aim for at least 12GB to 16GB of VRAM to handle modern high-resolution textures without stuttering.
Ask if it supports DLSS 3.5/4 (Nvidia), FSR 3+ (AMD), or XeSS (Intel). These AI-driven tools are essential for maintaining high frame rates in demanding titles.
High-end cards (like the
RTX 5080 or the 5090 ) can have significant power spikes. Ensure your power supply exceeds the "recommended" wattage by at least 100W for safety.
For example, AMD’s AM5 socket is expected to be supported through 2027+, allowing you to upgrade your CPU later without buying a new motherboard.
While not strictly necessary today, PCIe 5.0 slots for your GPU and SSD will be vital for next-generation hardware speeds.
This is a lifesaver for troubleshooting. If your dedicated GPU fails, integrated graphics allow you to still use your PC.
For 2026 builds, 6000MT/s is widely considered the ideal balance of speed and stability for both Intel and AMD
Ensure your primary drive is at least an NVMe Gen4 SSD to take advantage of technologies like DirectStorage, which significantly reduces game loading times.
Check if the motherboard has at least two M.2 slots and four RAM slots so you aren't forced to replace current parts just to expand.
2026-era cards are often over 330mm long. Verify your case can physically fit the card you've chosen.
Many "budget" cases only include one fan. Ask if you need to buy an extra 3-pack of 120mm fans to ensure proper airflow.
