Just got my titan x yesterday. Found a good deal on a very slightly used one for $875. The full cover EK block arrived today (crazy fast shipping from Slovenia!) and installed without a problem. Card overclocks great and runs cool under water. I have been using SLI setups for about 5 years now, went from 2 gtx580's to a gtx690. I am happy to be back to a single GPU. settled on +250 core +500 memory for the moment, not too shabby. I have seen it boost up to around 1470 or so.
