Well the new PC runs A18 at 1080p on all high settings with Vsync on at a solid 60FPS most of the time until I enter a city and forcefully look around at the tallest buildings and it will drop to maybe 40FPS, so I am definitely OK with that, although bloodmoon will be interesting to see.
I will just keep the CPU @ stock clocks, as Fox said if it ain't broke don't fix it - in so many words anyway. I thought Metro 2033 Redux was a good benchmark, I guess even it is older tech now. I usually run Crysis 1 when I upgrade which is a favorite benchmark of mine and it was amazing to see how fast it was during the benchmark run, of course Crysis and Quake III Team Arena benchmarks are just for kicks and I do not take them seriously. I ran S.T.A.L.K.E.R. Call of Pripyat benchmark as well which utilizes some more graphical options like SSAO and Tesselation, of which I really had no Idea about until I got my GTX 1080.
All in all the upgrade was a major help with 7 Days to Die and when Dying Light 2 and S.T.A.L.K.E.R. 2 come out I will be ready for them.
