Buy a 8800gt in a weeks time, should cost only a LITTLE more then the 8600gts, but it will not only ride you over for like 4-5 months, it will run those newest games just fine too. As for the CPU, when overclocking it's Intel hands down, at stock speeds the e6750 is faster then the x2 6000+. So depending on how much cheaper the x2 6000+ is, I'd say Intel.
