Hate to rain on your parade, but the CLA2MX has the same memory bandwidth -- 1.6Gb/s, I think -- as a generic GF2MX with SDR-SDRAM, because the DDR-SDRAM is using a 64-bit data path whereas the SDR-SDRAM on most other GF2MXs uses a 128-bit data path.
Add to that the fact that the DDR-SDRAM is clocked at 143MHz (286 "effective" MHz), and uses 7ns DDR-SDRAM, whereas most SDR GF2MXs use 166MHz, 6ns SDRAM, and you're looking at a card that has slower, less overclockable memory. The fact that the memory is DDR amounts to marketing drivel.
Do you REALLY think that nVidia would do something as stupid as releasing a budget card that supported 128-bit data path DDR-SDRAM? That would cut directly into sales of GF2GTS-based cards.
Oh, one other item -- you can get a Visiontek or eVGA SDR GeForce2MX 32mb card for about $90 plus shipping online. They both use (last I checked) 6ns SDRAM, and outperform the Creative Labs card both out of the box and when overclocked. 'Nuff said.
