Your PC not keeping up anymore? Before you buy a whole new machine, talk to us. Most gaming computers can be meaningfully improved with a single targeted upgrade — and LithGeek in Lithgow will tell you exactly what’s worth spending money on and what isn’t.
Gaming PC Upgrades We Do
🎮 GPU Upgrade (Graphics Card)
The single most impactful upgrade for most gamers. A new graphics card can double your frame rate, unlock 1440p or 4K gaming, and give an older system years more life. We source and install GPUs, check PSU compatibility, and benchmark before handover so you know exactly what you’re getting.
Common signs you need a GPU upgrade: frame rates dropping in newer games, can’t hit 60fps at your preferred settings, can no longer run a game at a playable quality level.
🧠 RAM Upgrade
Still on 8GB RAM? Upgrading to 16GB or 32GB is one of the cheapest and most noticeable improvements you can make — especially for open-world games, streaming, and running multiple apps. We check your motherboard’s maximum supported RAM and speed before recommending anything.
💾 SSD Upgrade
Still running games from a hard drive? An SSD upgrade is transformative — drastically faster load times, smoother open-world streaming, and a noticeably more responsive system overall. We install NVMe SSDs (the fastest type), migrate your existing data, and make sure everything is running correctly before you pick it up.
⚡ PSU Upgrade (Power Supply)
If you want a better GPU but your current power supply can’t handle it, we can replace it. We select a unit with the right wattage and connectors for your system — including support for the latest 16-pin GPU connectors on RTX 40/50 series cards.
🌡️ Cooling Upgrade
Thermal throttling is a hidden performance killer — your CPU or GPU slowing itself down because it’s running too hot. We diagnose thermal performance, clean existing heatsinks, replace dried thermal paste, and install better cooling (including AIO liquid coolers) to get your system running at its proper speed again.
🖥️ Full System Refresh
Sometimes the right move is replacing the CPU, motherboard, and RAM all at once — a platform upgrade that gives your existing GPU and storage a new lease of life. We’ll tell you honestly whether an upgrade makes financial sense or whether building new is the better call.
How It Works
- Bring your PC in (or call to discuss) — we assess what you have and what bottleneck is limiting your performance
- We give you an honest recommendation — what’s worth upgrading, what it’ll cost, and what improvement to expect
- We source and install — we handle the part, the installation, cable management, and testing
- You collect a faster machine — benchmarked and verified before handover
We will always tell you if an upgrade isn’t worth it for your system. If your machine is genuinely past the point of worthwhile upgrades, we’ll say so — and we can talk about a new custom build instead.
Frequently Asked Questions
Is it worth upgrading my old gaming PC?
Often yes — a GPU swap, RAM upgrade, or SSD install can breathe years of new life into a system for a fraction of a new build’s cost. We’ll give you an honest assessment of what’s worth doing and what isn’t based on what you have and what games you play.
What is the most worthwhile gaming PC upgrade?
For most gamers, it’s the GPU — it directly determines frame rate and visual quality in games. RAM is often the cheapest improvement. An SSD upgrade is the most noticeable day-to-day improvement if you’re still running a hard drive. We’ll diagnose your specific bottleneck before recommending anything.
Can you upgrade a prebuilt gaming PC?
Sometimes — it depends on the machine. Some retail prebuilts use proprietary cases or undersized PSUs that limit upgrade options. Bring it in and we’ll assess what’s possible before you spend money on a part that won’t fit.
