Cheers mate. So for example, if i bought a 2.4ghz Quad - i would see a difference over my 2.4 Dual core with a game such a Diablo 3? Somewhere i heard that many games don't utilize more than 2 cores anyway, but i'm probably wrong!
yeah the Q6600 even at stock is good. im sure you'll notice performance increase. you just need to pair it with a good gpu. and you can also overclock the Q6600 easily to 3.0GHz without changing the voltage (depends on the chip though). you just gotta make sure you get a G0 stepping one for the Q6600.
