Ok my rig is a 3500+ newcastle, geforce 6800 gt (AGP), and a gig of value RAM. I built this thing 2 years ago and it is seriously aging. I want to upgrade for maybe $500 so I would get a new mobo, another gig of ram, and probably a Geforce 7900 or x1800. Would this be smart or should I try and wait until Conroe or the Am3 comes out? Also I'm scared that the CPU would limit the New GPU (7900,x1800)! This is another big problem. I'll check back tomorrow to see what was said. It's LATE.
