That is on SICK cooler dude...here's some specs that I found:
"A universal clip helps insure compatibility with both nVidia based and ATI based video cards."
(1) The video cards without the heatsink mounting holes or with components that interfere with the heatsink cannot accommodate this product. (2) The heatsink occupies an adjacent PCI slot. (3) If the components on the video card interfere in any way with the heatsink components, you cannot use this heatsink. In such a case, you should immediately stop installation and return the product. (4) This heatsink if quite large at ~4.5" wide. It will add some height to the top of the video card when installed. In some thin cases such as the Casper II this may make it impossible to reinstall the video card. Make sure your case has space above the card slots before deciding to use this cooler.
It would be nice if ThermakTake listed known cards that simply don't work with it...
And here's a decent review link going over the finer points:
