Core2 Quad Q6600		vs	Phenom II X4 955

	8.0 read review		8.0 read review	But in terms of a re-encode/compress test and Stalker at 800 x 600, and it's quite apparent what two extra cores can do. Core2 Quad Q6600

	9.4 read review		8.7 read review	Unfortunately because it is old and there have been many new releases, 1366 1156, 1155 and now 2011, it is quite hard to recommend it, however if you do own one already I would always say don't get rid of it, keep it as a backup rig, this was truly one of those chips that could take a lot.
