X2 4200+ worth picking up as an upgrade?
I was considering picking up an X2 4200+ Manchester for $200 while I still can and potentially adding a 10,000 RPM Raptor HD to my system that I would run my games from. I would also plan on overclocking the 4200+ to hopefully get at least a couple hundred extra mhz out of it. Does this sound like a worthy investment over my 3200+ single core 2.0 ghz (oc'd to 2.35) or just a waste of money?
