I do very little gaming, but its something that I like to partake in then and now when I have the time. I'm considering buying a 20" 2.4 Ghz iMac with 2 GB of RAM and installing either XP or Vista through bootcamp. Personally, since I'll be using the Windows partition occasionally at best, I want to minimize my expense on it. I'd really like to go with Vista Home, as I have no need for any of the OS features whatsoever. However, is there any limitation in Vista Home that's going to affect gaming performance? Should I consider Home Premium or higher? My understanding is that Vista in the long run will be a bit better for game performance and I've heard positive things about DirectX10.
