As always it is all about the build of your PC, the average computer is going to get wrecked by this game. However the other top 5% of machines out there we are drooling over this game and we are happy campers.
This game is similar to the release of the original Crysis it hammered every piece of hardware out there besides the top end users. Ubisoft has done the same thing this game is pushing the limits of next gen to the max.
Here is my gameplay so far I only do intro commentary. Running i7 3770k, 16gb ram, and gtx 980 on 1440p maxed settings between 40-60fps. I did have to change my codec after the first few videos to smooth it out and get a little better quality so watching Sequence 2 Memory 2 or 3 and after runs very smooth and great quality =)
