Well, I never said oc'ing... If I oc'ed a 6800gt senseless, I could almost achieve 2.5x. With a liquid cooled gpu, I could so far past any benchmarks, almost to a 7800gtx. If I ever could use phase change cooling... haha dual 7800gtx.. think about that. But yeah. Money_man, I'm positive your dual 6600gt's (oc'ed) could smack any stock 6800gt.
