I would like to hear some personal experiences of gaming with Windows 8. I have no plans to install it as I do not like the interface. However, I am curious to hear about your experiences running games. If I hear good reports for a few months, perhaps I will change my mind. But for now, I'm very happy with Windows 7.
Anyway,
Tom's Hardware did testing on Windows 8 and found the following:

Of the 10 games we benchmarked, one one demonstrated a significant difference in moving from Windows 7 to Windows 8, and only on Nvidia's GeForce GTX 660. That game was Borderlands 2, where our average measured frame rate dropped from 86.6 to 81 FPS. But at that speed, the five-frame drop is hardly worth fretting over.More bothersome was the compatibility issue we ran into in Sleeping Dogs, which affected Windows 8, but not Windows 7. When we chose the High detail preset, most of the in-game models simply disappeared. Fortunately, that geometry shows up again if you dial down the graphics quality. Hardly a favorable solution, but it's what we have for now.
Aside from those couple of idiosyncrasies, performance under Windows 8 is indistinguishable from Windows 7. Any speed-up or slow-down would be almost impossible to identify during game play, and we expect compatibility issues to get patched quickly by game developers.
Overall, they tested 10 games, but I'm going to mostly try to stick with the results that were more than 1 frame per second different:
Batman: Arkham City. About one frame advantage Windows 8.
Battlefield 3. About two frame advantage to Windows 8.
Borderlands 2. Five frame advantage Windows 7 using GTX 660. One frame advantage using Windows 8 with a Radeon 7850.
Crysis 2. Less than 1 frame difference regardless of video card. Windows 7 did better with Radeon, Windows 8 did better with GeForce.
Metro 2033. Both GeForce and Radeon performed better under Windows 7, by about 2 frames per second.
Sleeping Dogs. At high resolutions, it is unplayable in Windows 8.
World of Warcraft. About one frame faster on Windows 8.
Most other games had less than one frame per second difference between Win 7 and Win 8.
Overall, one frame per second is not enough for me to upgrade, especially when Sleeping Dogs, Metro 2033, and Borderlands 2 appear to have trouble on Windows 8. Maybe patches will work this out at some point. I'm not really a Windows 8 fan, but I was hoping that some of the performance gain rumors would be true. Sadly, they do not appear to be true.
