ok, I was gonna say, that score is deceptive. If you OC'd the Gt's I wonder what you would get. or if they had better coolers, like.. GTS 512..
how come your cpu is only at 3.15? benchmark that thing much higher! you could go way up in score I bet.. prob 18 or maybe 19K. specially with OC'd Gt's.
want to upgrade your rig? I will buy your cpu
