I did a search and couldn't find any reviews. I have installed 3d power MX and an MX VO into Duron based systems and they work fine. the MX came with a Heatsink and the MX VO came with a Heatsink and Fan.
I would suspect that the 3d Power is fairly middle of the road MX, Elsa is a bit better but too costly over 3d Power.
