The GeForce 4 MX is a lot faster than the 2 MX, but it's most definitely NOT going to run Doom 3 smoothly at 1280x1024, and you'll miss out on the pixel shader effects that are required to use full detail.
If you're familiar with Windows versions of nVidia's cards, the GF4 MX in your dual-867 is about as fast and feature-equipped as the GF2 Ultra, though of course that had 64 MB of memory on it (and was much more expensive when new).
The GF4 MX you have is actually pretty unique, since (outside of the 17" widescreen iMac) all GF4 MX models are otherwise 64 MB, including the one that was available before the current PowerMac iteration.
