I'm looking to put together a PC for gaming in my living room using parts from my girlfriend's old computer. I want to get the best value while still being able to play various games at 4K resolution, ideally at medium to high settings. Some of the titles I'm interested in include Switch emulators for games like Mario Party and Breath of the Wild, along with titles such as Silent Hill 2 (remake), Resident Evil 2 and 4 (remakes), Red Dead Redemption II, and a few others.
Here's what I have to work with: a Ryzen 7 3700X, a Gigabyte X570I AORUS PRO WIFI motherboard, 16GB of DDR4-2666 RAM, and a Zotac RTX 2070 Mini. I'm planning to sell the CPU and GPU and possibly the motherboard, and I can throw in around £500 more for upgrades. I'm considering a Ryzen 5 5500X3D with a new GPU, possibly the AMD 6950 XT or something in that range. I want to know if I'm on the right track or if there's a better combination of parts for 4K gaming within my budget.

To be honest, 4K gaming on a budget like yours can be tricky. You'll likely need some sort of upscaling to keep decent framerates in newer titles. I'd recommend leaning toward an Nvidia GPU since their DLSS technology is really good right now for 4K gaming. You might want to consider at least a Ryzen 5 5600X to avoid bottlenecks, though the GPU is often where the real limitation will hit you at that resolution.
I would suggest building everything except for the GPU first, then test the performance with your TV. Most TVs only support 50/60Hz, which could limit your experience. The AMD 6950 XT would definitely be a solid upgrade if the 2070 doesn't cut it for 4K.
Exactly, it’s all about that GPU for 4K; the rest might not matter much!
You might not need an X-series motherboard for your setup unless you're looking to utilize specific features. They can be pricey without providing significant benefits for your build. Also, the Zotac 2070 Mini may struggle, so selling it for a 6900XT might be worth it if overall performance is a concern.

Totally agree, 4K is demanding. Make sure your new GPU supports DLSS for better performance!
