Cybertron is cheaper than building yourself and mine used excellent parts. Not true top tier stuff, but excellent nonetheless. I would not get a GPU "lower" than a 4070Ti today, and really, the 4080S is the price/performance sweet spot. It sounds like $800 is a bit light unless you quickly want to be capped out. I try to keep my PC's for 5-8 years before I have to turn settings down from "Ultra" to achieve 80fps avg. without the 1%'s killing me.
