performance wise,, bah its only slightly faster and has better memory management.
there is absolutely no difference between XP pro and XP 64,,,, just wait til that beastly overbloated hog Longhorn comes out in about 30 yrs.....
ive tried XP 64 Mandrake 64 Suse 64 Fedora core 64 all of them and well nothing,,, all your gunna do is run into hardware and software issues. XP 64 is good cuz it will run 32bit apps. but hardware and software makers arent up to speed yet.
although with the hardware in my sig i have all the drivers i need. Creative even made 64bit drivers. which worked flawlessly for me.
im curious to see how Chronicles of Riddick runs in its 64bit mode. Too bad i have the xbox version and cant justify buying the pc version just for 64bit mode.
