I've had this PC for a while now, and I need a processor, preferably dual core so as to run games at a good rate without a slide-show.

The motherboard I have is an Abit Nf7 i believe. The processor I have right now is an AMD Athlong XP 1500+ ( It is 1.3 GHZ ). For the processor I need something that is cheap and not too expensive, and fast. Cheap and fast. Recommendations?

Another thing, where can i buy an xbox 360 power chord for the cheap?
