Which Arctic Cooling Silencer for 9800 Pro

I thought I would pick one of these up but I notice there are 2 that fit 9800 Pros. VGA Silencer Rev3 and ATI Silencer 1. The ATI Silencer 1 I believe is newer and costs an extra $10. Is it worth it over the VGA Silencer?

My brother has a vga silencer rev3 and it works great. There is also more solid aluminum mass. I would just go with it.

the rev3 is fine. the only difference i believe is that the ATI silencer 1 can be used with the X800's. I had a rev3 on my 9700pro and loved it, and it was silent to boot.
