Definitely not. The 7700 is definitely good enough.
I haven’t seen benchmarks but I’m willing to bet a lot real world gaming difference will be in the 5% range in gains.
you got a 1080 at a fantastic price, stick with that..
let’s be realistic. Outside of gaming your CPU is sitting idle 95% of the time. In games, the GPU is doing the majority of the work. either CPU is fast enough to supply that 1080 with all the data it needs. *
