Hi there, I'm glad Steam for Mac is out, but to be honest it does not work as well as on Windows. My question is, which is better for gaming. Windows XP or Windows 7? I would mainly play games like: - Source games (Counter-Strike, Team Fortress, Garrys Mod, Left 4 Dead etc) - Battlefield Bad Company 2 - Modern Warfare 2 My thought on Windows XP would be that it's lighter therefor possible better gaming performance. My thought on Windows 7 would be that it has up to date drivers, which games would take advantage from, therefor increasing the gaming performance. My System: 15" MacBook Pro - Late 2008 2.8GHz Intel Core 2 Duo 4GB Ram NVidia GeForce 9600M GT So what should it be, XP or 7?
