ok so im getting a new computer and i have two choices. they are both microtel and prebuilt so i cant pick and choose parts. The first contains a gtx 680 GPU with a amd phenom II 965 CPU. The second contains a gtx 670 GPU and an I7 3770k CPU. all the other specs in the comp are the same except the gtx 670 computer has liquid cooling. so my concern is will the gtx 680 be bottlnecked by its cpu? or should i stick with the 670 and a better proccesor. i play games like WoW BF3 Skyrim Crisis etc. any help is appreciated. thank you
