So I was given an old computer, it has an Athlon 64 3000+ CPU, Asus K8N8XLA mobo, 512mb of ddr ram, and a Geforce FX 5200 AGP graphics card. I did a little digging around and I guess the 5200 is pretty much straight garbage. Could I turn this into a decent XP gaming rig? 2 gb of DDR is 5 bucks on ebay, but what is the most cost effective AGP card? I guess I could root around for a CPU upgrade too, is there a marked difference between a 3000+ and a 3400+? Looks Like I could get a 3400+ for abour $30.
