I saw on Hot Hardware today that there will be two versions of the Geforce FX:

GeForce FX 5800 Ultra--500 Mhz core, 1GHz memory clock-- Many of our board venders have quoted $399 (US) as the price for their GeForce FX Ultra boards

GeForce FX 5800--400MHz core, 800MHz memory clock--this will be priced at a lower price point than the GeForce FX 5800 Ultra.

The card I checked out at Comdex was the high-end "Ultra" version...
