I'm still using Windows XP, but I need to assemble a new computer soon so that I will be able to play new computer games. I've never used Windows Vista, Windows 7, or Windows 8. My only priority with an operating system is how well I am able to play new computer games for the PC with it. Is Windows 7 or Windows 8 any better than the other for playing new computer games for the PC? Are there any compatibility issues with being able to run any new computer games on either operating system? Do computer games run any faster on either operating system? In general, is either operating system better than the other? If so, why? I am tempted to get Windows 8 because it is the newest Windows operating system, which makes me believe that I won't have to replace it with a newer operating system as soon as I would have to with Windows 7, but my understanding is that Windows 8 is an operating system designed for tablets (and smart phones?), whereas I will be assembling a desktop computer whose primary purpose is to be able to play new computer games as fast and as hassle-free as possible. I would appreciate any advice on the matter.
