Well, as a current Matrox card user I have to chime in here. I have the exact card mentioned by Kev999 - the 690 PCIe. (128Mb VRAM). Ran 8.5Producer in WinXp (32bit) no problems, and have now switched to Win7 (64bit) and X1 Producer. No problems so far, and yes, it looks great. Running dual LCD monitors. The Matrox cards
do not support Aero however and because of this and their price I probably wouldn't buy it again. But just so people know, if you have this card (and don't need Aero) it seems to be working fine in X1. Seth - is there a specific situation where SONAR X1 Producer might utilize 1Gb of video ram? Just curious - thanks
