Sheezy,
Using Linux for major gaming is a horrible choice.
Why go through the hassle of finding out how to set up every single game, which not all of them are compatible with wine; when you could go on windows, which isn't that slower if you account for setting up time in Linux, and everything is compatible(or at least everything that matters) and it works well?
Also about how Linux has almost no viruses (come on, there has to be at least one) is irrelevant to anyone with common sense.
I've had this computer (using Windows Vista for the first part then using Windows 7 when it started with Build 7000) since the start of the year and I've had no viruses at all even though I've pirated over 128 things and have gone to many different research sites.
Like RW said (sort of), I would only use Linux if I wasn't gaming, like doing media or just for hosting a server.
