ok i'm water cooling a rig i just built for myself and i went on EK's website and went through the configurator. it said for my gtx 660 ti's (evga FTW 2 gig signature) a gtx 680 water block would work. is this true or should i try another website?

from what's available, The GTX 660Ti utilizes the same PCB of a GTX 670, however, this bit of info should be taken with a teaspoon of salt as there's always bound to be PCB revisions, re-revisions by manufacturers or board makers.
