Pretty new to the whole Mac platform.. usually use my xbox to play most games these days due to friends playing over xbox... got plenty of PC games sat in the corner, Grid, Crysis, Cod2, Cod4 etc.. I fancy testing this 27inch IMAC with a few decent games.. using bootcamp or I may even invest in Para Desktop.. but for now lets focus on bootcamp, out of experience or knowledge what would perform better overall games wise? speed, fps.. those sort of factors Windows 7 or XP .. does have knowledge to share on this respect?.. Thanks!
