I have always been an AMD person, but I am looking into building my own computer and I am wondering which processor to buy.

I am planning on buying an ATI graphics card, and I am wondering if either processor works better with one or the other. I have found that AMD processors are generally cheaper, but is this always true or is this just because of the sites I looked on. I have mainly used newegg and circuitcity.com. I want to buy a quadcore processor.

So my question is.... should I buy an AMD or Intel Quad Core Processor. Any recommendations would be greatly appreciated.

Thanks in advance.
