GruntvillE.com checked out the Zalman VF900-Cu GPU Heatsink

I must say that the installation section of the manual is very detailed. I was amazed to see clear illustrations with each and every piece of the h eatsink numbered and referenced. This heatsink is designed to be used by both of the popular platforms; ATI and NVIDIA. You can use the VF900 with ATI models 9000 and newer minus the popular 9600 and 9550 series. With NVIDIA, you can use the sink with a GF4 card or newer except for the AGP version of the 6600. That's a lot of video cards and I'm sure you'd be hard pressed to find another heatsink that can support this many late model cards.
