I was wondering if anybody has gone from Microsoft Vista back to XP and did they see an improvement? I have been suffering from a lagging computer during active market hours ever since i got this new computer. XP seems to be a resource hog. I do have 2 gigs of ram but this doesn't seem to be enough. My system consist of 4 monitors (one 30" and three 17"). On my old computer I used to run 5 monitors and ran with out any lag what's so ever. I only had 1 gig of ram, but was under Windows XP. I am seriously considering down grading back to XP. I really appreciate any help.
