Win8 is faster so you get better performance in games.
Really Win8 is exactly the same as Win7 except the start menu goes fullscreen now. That's the only difference. The rest of the garbage you hear like the post above is due to ignorance.
Nope the 'faster' thing here is boot up and shut down time which almost no one cares about. Frame rates in games do not get affected by that in any major way (I don't mean 2-3 FPS).
And that is not due to ignorance but due to my experience with it. Its worst factor is the fact that it is way too difficult to use and takes a lot of time to figure out. The most irritating things are its four corner gestures, searching issues, corrupted windows applications (In some PCs), application closing commands, etc. Overall these and many others make the experience very unpleasant.
You have to keep it in mind that Windows 8 was specifically designed for Touch based PCs and Tablets. Overall experience would suck with a keyboard and mouse. So its a good idea to wait for Windows 8.1 or 9 and stick to Windows 7 for a while.
I myself bought it out of curiosity to try new stuff but now that I am stuck with it since last 3-4 months. Can't even delete because all of my games are on C drive and downloading them again off steam would take me ages due to slow internet.
