i found a site w/ the VGA heatsink. It doesn't post any test or anything, so im interested to see if anyone else has it. I cant find any other sites, but overclockerscafe gave it an editor's choice so it must be somewhat good right?
heres the link: http://www.overclockercafe.com/Reviews/other_misc/Bigwater_Accessories/
if your not a hardcore gamer/overclocker, it's not really neccessary to get water cooling. Where i live, water cooling overkill... and also you gotta make sure your case is large enough for all the tubing
