According to some 3D benchmark tests, the 2900 XT performed slightly less than the 8800 GTX. However, ATi is yet to release updates for the Catalyst Software that the 2900 runs on, which means that in the next couple of months it may surpass the 8800 GTX.

The definite good side though.......the 2900 XT costs around USD $150 [/i]LESS[/i] than the GTX!

According to those benchmarks, Nvidia seems to have somewhat of a lead. Hopefully though once ATI updates the Catalyst Software, I think the 2900 XT will soar past, considering that it has way better hardware specs than even the 8800 GTX.

Theoretically, do the specs of the new ATI cards promise better HD-DVD playback than Nvidia?

Since this card is much cheaper than a GTX, you can always do CrossFire and it'll be a gig lol

OK well that long list of whatever left me dumbfounded but the complexity must indicate something really good. :D

Well, it has 320 stream processors, 700 Million transistors, 512MB of RAM, 512-bit interface, 750 MHz core, 1650Mhz Memory GDDR3, and DX10. All of these are basically better than an Nvidia 8800 GTX, so yeah, it's really good :) The rest doesn't really matter until ATI updates the Catalyst and other software to take full advantage of the computing power.

Yes, ATI has released the 2900XT and they claim that soon other versions will be available with GDDR4 memory and other options. Most of them are priced at between USD $400 and $450. ATI has also been offering game vouchers with the cards that include Half Life 2 and other games.
