85 bucks, not the best processor but it's pretty good should last you a couple years before it starts to get slow. Also maybe get some more ram, if you're gona be gaming then get a video card.
okay I had a celeron 2.2 GHz and a 700 mhz p3 was faster.
I sudgest the Processor that Juice linked.
You can't get a c2d because socket 478 does not support them
