Quick question - assuming you're running Windows on the machine with your GeForce 4 MX, what is DVD playback like on it, how high is the CPU usage on it?
I got a GF2 MX for my parents' machine, and the MX model doesn't appear to have the MPEG-2 decoding stuff on it, whereas the GF2 GTS I used to have did. CPU usage was very high (95 ~ 100%) on the machine using the MX card, and about 25% on a P3-866 machine with the GTS.
