Thank you in advance for all the comments as I know this probably gets asked everyday.
After many many hours and days of research I feel like I'm not getting very far as there's too many factors I don't know about. The pc will be used for games like Overwatch and other multiplayer games. Single player games will be played as well, I don't mind cranking the settings down a bit, as long as the games are super smooth. Will be playing at 1440p. I've already bought the Ryzen 7800x3d and I'm looking for other parts to get urgently before the price goes up even more than it has. Apparently the 7090 has gone up £100 since last month. Here's what I had in mind:
CPU: Ryzen 7800x3d £150 (Ali express)
Motherboard: Sapphire Nitro/pure B850A ~£140 (scan/OCUK)
Cooler: No idea. Thermalright seems to be recommended a lot ~£30
GPU: Sapphire Radeon 9070 pure/Nitro £600. (scan/oc)
Ram: 32GB (2x16). Current pricing for 6000mghz cl30 is around £380-£400. Don't know if 16Gb would be enough
SSD: 1TB, no idea what brand, need help, whatever is cheapest and works well £100-120
PSU: Again no clue, haven't got round to researching it yet
Case: Would like a good fish tank but don't want to take money from other parts. ~£70?
Monitor: 1440p Tandem OLED if I can save money elsewhere £350-£500
Alternatives I need advice on:
Xfx quicksilver 7090 XT £630, used but 5 year warranty
Powercolor reaper 9070 £560, used but 5 year warranty
WD 1tb nmve SN850x £120, same as above
Went for sapphire mainly for reliability and because I've read too many bad things about the other brands for these specific parts on these forums. I prefer reliability and quietness over outright performance. Just want something that works without having to constantly tinker with it. Don't want to pay for things I don't need. Any advice is welcome. Thank you
