Hi, i'm currently deciding whether to download Windows 7 or XP on my Mac Air 13 to play games. My question is does XP really run faster? Also, does the DX10 update in Windows 7 make a large difference when playing games? Will the fact that i'm using a Mac Air 13 make a difference when using bootcamp such as lag? Information: Game: League of Legends (If it makes a difference) Model: Macbook Air 13 (The newest model) Help appreciated!
