Well I tell you in simple words Vista is totally Reborn Windows with so much changes that XP can not be transformed to it. Secondly it is so heavy for a budget system that it is not good for games without a heavy system. In all aspects Vista is superior than XP but you should have system capable of handling it. In terms of game play the new direct X 10 technology is not available in Xp but for now there are very few games built for dx10. So if you have good system go for Vista simply!
i prefer windows XP , why?
Because is more fastes , dont requiered a SUPER COMPUTER, which 512ram in xp i can do wonderfull things , in VISTA wich 512 ram i cando NOTHING. GREETHINGS
in this moment i prefer XP, why? Cause lot of programs, like Games That Works Perfect on XP, doesn't Works on Vista, so Thats something i DOn't Like from Vista.
look it's different between prefer and use, i prefer vista , still have some bugs but it's great and xp had alot of bugs when released , but iam use xp caus my pc is too low equip.
