Oh, whoops. I would say definately upgrade to a quadcore then, maybe even something AMD if your looking to not waste money on something you cant really upgrade.no the cpu is a e6600, not a q6600
two 9800gtx in sli are quite a bit better than a single gtx260Yeah I would upgrade the CPU then snag a cheap GTX 260 on craigslist. I did it and I can't complain ^-^
