pretty cool. my room mate's putting together a danger den water cooling system in a stacker case. I've only got a thermalright massive mofuggin' ninja tower style heatsink on my cpu. Good enough for me considering my 320mb vidcard is now the bottleneck. Decided on it vs the 640mb to save $80 or so. Back when I got it the 320mb was scoring higher on the benchmarks anyways but now that crysis is out the 640 performs SO much better.
