Are you drunk? Where are you getting one for £500?
Is this still a deal at 1899? Seems it's gone up on their website. Also does it need more storage? If so what's the recommendation?
Genuine question Whilst I know for certain in terms of GPU a 3080 vs a 1080 would see huge FPS increase at 1440 144mhz I am however uncertain if my slightly aged CPU (6700k i7 Skylake, clocked at 4.2Ghz) would see much gain from upgrading it It seems marginal from my research and pottentially money thrown away (purely a gaming rig, with minor office work)
Do you have anything right now? Or does that £2k need to include monitor, keyboard, mouse etc? Also, what are you going to be using it for? All well and good slapping a Ryzen 3900x, but if you're only using it for gaming it'll be a complete waste of money.
3080 start at £650 for founders and I've seen them go up to £850
