I was wondering if it would fit first of all. Zalman says it will fit on anything with mounting holes around the gpu. Do ATI cards have these holes? What performance increases have you seen on your overclock and running temperatures? I wanted to wait for the new VGA silencer, I got an e-mail back from them saying they would have one for the 9800xt on the market, but that was months ago and I have still heard nothing about it.
