Yeah your RAM won't transfer over to a new motherboard. But 2x1gb can be had for like $40. I don't know about prices for people outside the US so I can't be of much help.
if ur not gonna overclock go out and buy one of those Comps that have the q6600 already in them... anywhere from 2-3 gb of ram, and come with usually a 8400 gs...
All you would have to do is replace that video card and theres your rig
