First off my goal is to gain Gaming Performance. I have mobo MS-6378X-L. The specs say (Athlon XP up to 2000+). I'm hoping Im wrong but that means the "Limit" is an XP 2000+ right? If so then would an additional stick of 512mb help in gaming performance? or should I save for a better Video card? If not, what is the CPU limit? And would the CPU > 512mb RAM?
