^ I second what Jahid says. Although the gaming for Linux is improving (GOG.com just announced Linux ports coming this fall, Steam has a bunch of Linux games & SteamOS, etc), there are still some games that I like to play which are simply not supported on Linux at all, through any method. I dual boot with Win7 for such cases. Gaming is the only time I use Windows, the rest of the time I boot into Linux. You might concider this option, as it will let you have your cake and eat it too.

I am a n00b! Please assume zero knowledge on my part. Sorry for any dumb questions, I am still learning.
