Reviews Word on the street

Core2 Quad Q6600  vs Core i5 750 

Somehow, however, this plucky little quad remains relevant, especially if gaming grunt is high on your list of priorities.
Core i5 750

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.
