I have a Quad core q6600 the link to my cmp is right there. http://www.amazon.com/HP-Pavilion-M9150F-Desktop-Processor/dp/B0010DQFF0.. The graphics card I am getting is right here. http://www.newegg.com/Product/Product.aspx?Item=N82E16814130616 If there is anything else that would affect my performance please tell me. I am wondering if the PCI thingy will also because of the cmp not having a PCI express 2.0
