Dual Core Optimizer

Hey guyz, for those who have AMD dual cores, is it even worth installing DCO on windows 7?!?

AMD Dual Core Optimizer

So if i don't use DCO, do i need to set affinity for the games i play?

That is not needed on Vista or 7, its only for XP users. Its funny that I found this installed on my rig though, some old game must have force installed it lol
