I just ordered the new MBP (2.53G, 4GB RAM, 512 vRAM) and I'd like to get back into casual gaming (current computer can't handle it). Here are my questions: - Can this new MBP comfortably run COD4 on max settings? - Is there a performance difference running the game under Leopard as opposed to XP? - Is it advisable to install XP via bootcamp for gaming? I'd rather keep XP off the machine entirely unless it makes a performance difference. I'll probably be playing 3 games at the most (i.e. I can wait for Mac releases). My favourite game of all time is 'Return to Castle Wolfenstein', so I want a few games similar to that (hence COD4). If installing XP is advisable, then I may hold off COD4 and just buy COD5 when it comes out in Nov. Any idea why COD5 isn't being released for Mac? Thanks for the help and sorry for the noob questions!
