BigMack70 :
Probably just got a dud card but you shouldn't really be buying the GTX 6xx cards if overclocking is your priority anyways
I know you are a AMD Fanboy.
And you have a rival card (HD 7970)
But Misguiding people that GTX is a poor Overclocker is Not good. And everyone knows it
MSI Power Edition overclocks very Good.
Maybe he got a Dud, but he can replace and get a Original card and OC it high.
He wants good performance and a GTX670 is the
Best Bang for the Buck in that Range.
And Maybe you have listed a Performance chart
(In another thread) showing that 7950 is now smoother like GTX660Ti.
But still Nvidia has Physx, TXAA and Adaptive V-sync. Which enhance gameplay.
And the real matter behind Buying a Expensive GPU is a Good Gameplay
