Hi, yes i know this question has been asked many, many times before, but i am still unsure. I am currently using Windows XP pro x86, windows xp is good enough, but will i see any improvments in performance if i switch to Vista Ultimate X86 if i configure and tweek it correctly? I know people say vista eats RAM but i have 4GB of RAM so surley with the maximum a 32bit OS will handle RAM won't be a problem. I have used vista before but wasn't happy with performance, but at the time i had a very differant setup (3.0GHz Pentium 4, 1GB DDR 400 RAM, nvidia geforce 6600 256mb) The reason i am seriously thinking of switching is because 1.XP isn't going to be supported forever 2. its looks amaizing 3. most software and games are now designed around windows vista so anyways, what y'all think i should do? ps. time, effort and money (no i'm not ritch , i use bittorent ) is not an issue with upgrading.
