yea, I thought about W7 but without any driver support didn't think it would be usable for games.
Actually, it's quite playable. I'm running it now. A lot of companies have beta drivers for w7, but it they don't, just use vista drivers and you're good to go.
I was using xp service pack 3 before this and it was stable like a rock. I loved it but after tasting windows 7, I don't think I'll be able to go back to xp as my mainstay OS.
That being said... While you'll be stuck at DX 9, with windows xp you can make full use out of any soundblaster cards you might have... vista and windows 7 nerf the hell out of them. I miss my full EAX support. I hate alchemy.
