Ah that doesnt sound too bad at all actually, thanks. What kind of lifespan am i looking at in the current climate with 7800 xt? I understand that it might be difficult to say, but generally speaking.If you're uncomfortable doing upgrades yourself, you can pay for PCS to do it, and it doesn't cost much either.
You'd only need to upgrade the GPU during the lifetime of the build, but you'd have the option to upgrade the processor and RAM should you wish to if your needs changed.
But a GPU upgrade is literally just plug and play, there's nothing to it. Takes 10 minutes.
