i plan on using parallels with XP for simple tasks. i'm considering whether i should get vista64 or XPSP2 for a dedicated gaming partition via bootcamp. the only new game i really want to play is Fallout 3, other than that I will probably just stick with Battlefield 2 and some older classics to get me by. i also plan on dedicating about maybe 24-32 GB to the partition. apparently vista64 sees all of the ram, but it is also a resource hog. i'm not overly amibitious with graphics i just want stability and consistency. should i spend an extra $100 on vista?
