Hello I have a bit old computer with the following configration and was wondering if I can run an 64x copy of xp on it: - P4, 1 MB cache, 2.8 GHz, pass 800. - 2 GB Ram, pass 400, dual channel. - ECS mother board, pass 800. - ATI 128 MB VGA Card. - 3 Hard Drives (160, 80, 40) GBs. Also does using 64x copy of XP allow me to use different applications or I should only install 64x copies? or does there is something I do not understand? The reason I am asking that a friend of mine told me that 64x of XP can support more rams and more hard drives and more stable and more fast. So all my hard drives are 32 now, so please correct and clear my points Thanks a lot
