For those of you who used Vista, you should believe me to be crazy by now. Thing is, I wanna play some windows exclusive games. But the only genuine windows i own is a 64bit vista cd. Is this fine for games, or should I upgrade to W7? ... or are there any... less legal ways I'm not familiar with? It is to my understanding that boot camp only works with genuine copies, while running a parallel windows without installing it on the hdd is less than ideal for games. Dota 2. Don't care about graphics, but performance is crucial.
