@AymCTLI think it’s best to work backwards on this. What resolution and at what refresh rate are planning to play at?
The 4070, especially the super variant, should be plenty for most people. You could always upgrade the gpu in 2-3 years and leave everything else alone.
Personally I have a 3070 for a 1440, 175hz monitor, and it stay’s pretty much locked at 170fps. It’ll dip if there’s a ton of stuff going on. I think that if I had a 4070 it would be plenty for myself. Of course the 4080 would be a little better, but diminishing returns.
Good luck. Let us know what you end up with.
edit: If you’re lucky enough to live near a microcenter, I’d highly recommend their powerspec house built PC’s. They’re priced really well, high end components, and the builds are clean.
