TECHNICALLY, right now a good dual-core such as an E8400 or E8500 can overclock to a higher speed and since the games don't utilize all cores the chip with the faster speed is better. an E8400 vs a Q6600 both overclocked the same would give similar results however the E8400 and E8500 can overclock almost a ghz higher on average making them better gamers. Right now and probably for a little while longer that is.
