i just reformatted my hd with XP SP2 and my XP install was corrupt, but to double check and make sure it wasnt the drive, i borrowed Vista Ultimate from a buddy and it installed and ran fine (which meant basically i need a new XP disk).
my intentions were to use vista to just troubleshoot the above problem. problem is, vista runs BETTER on my machine than XP did. i had a "vista like" sidebar and it showed my processor always hovered around 4-5% at idle, and my ram useage was around 40% at idle. now my processor is at 0-1% at idle and my ram useage is only 30-35%. Vista boots lightning fast, opening programs is faster than XP, searching for a file is instant. and here i used to be a "no dont get vista yet, issues, performance, yadda yadda" but i was just spouting what others told me. ive yet to run superpi or 3dmark06 to compare with this exact machine on XP since i havent downloaded them yet, but i doubt its going to make any difference.
I wont be uninstalling vista anytime soon. i dont see any reason to. its pretty and IMO its faster.
