for gaming, don't bother with quad core unless your main games are supreme commander and FSX. otherwise, buy an E8400 and overclock it to 4Ghz. and as boulard83 said, AMD's new phenom II's are actually good. the phenom II x3's are able to compete with the core 2 duo 45nm cpu's while still being able to overclock a fair bit. i just ordered a phenom x3 710, and from benchmarks i've seen, it's about dead even with the E8400, but has a one core advantage.
