I liked windows 8, I prefer it to 7. Sadly my mobo isn't supported...yet, so I can't install my chipset driver or audio driver. I do have a new GPU...AMD 6790 which there is a beta driver for it. So after a month of testing 8, I was surprisingly pleased with it. As for the gaming aspect, I could not tell if there was a significant difference between each OS as I don't have test rig for side by side comparisons.
