Actually performance-wise, the Geforce GTS-V does quite well vs MX-400. My 3DMark2001 scores (default benchmark) are 3441 on my Duron system and 4047 on my Athlon system.
As far as I can tell the "V" stands for value as the GTS-V is clocked slower than a standard GTS, 175/286 vs 200/333. However, you will have no trouble overclocking up to 200/333. Mine can go to 205/340 without artifacts. Higher GPU speeds seem to hinder performance. Higher memory speeds (up to 405mhz) produce artifacts. (Actually I'm amazed the memory runs this fast because there are so many artifacts. Maybe ramsinks will help).
The top scores scoring MX/MX-400's for all processors, at all speeds, default benchmark (1024x768, 32-bit color) at Madonion range from 4032-4860 (top 23 scores, as of 1/23/2002). Considering the top 3 scorers did not run all the tests then the top 20 scores range from 4032-4479. (I know the Geforce 2 series cards cannot run the Nature test, the Environment Bumpmap test, and the Pixel Shader test but those top 3 scorers skipped other tests).
For a bargain basement card, the GTS-V does quite well.
