ATI probably has a good reason to delay the card I bet, I don't think it was the driver but I'm really thinking it's the hardware that needed fixing and I believe thats what they have been working on the whole time.
Within due time, the 2900XT will improve dramatically with driver updates.
It only lacked a release to the consumer market to make any improvements to the drivers.
I hope so

I quoted you on that point earlier and attached my own question...Does that not count?

I don't thin 16x 16x has much of a difference as they probably don't utilize the whole 16x anyway. There probably isn't much of a difference anyway if they do.

Probably don't use the whole x16, x16, but at times need more bandwidth than the x8, x8 can deliver.
http://www.tomshardware.com/2007/03/...sis/page8.html

You see that x8 PCI-E bandwidth DOES limit an 8800GTS in several games, and even more so in professional 3D applications. Plus note that the games tested don't really push the card to the limits....

Also, know that the 2900XT on the market now is the 512MB version, and it's NOT the top dog! This card isn't supposed to compete with the 8800GTX. The 1024MB version will be the competitor for the 8800GTX


What me concerns is the question whether there will be x16, x16 motherboards for the Intel platform. For that to happen, there will need to be a chipset that supports Crossfire (nope, the newest Intel chipset still runs x16, x4... check the Asus P5K and P5K3 specs), or AMD will have to create drivers that allow Crossfire on ANY motherboard with dual PCI-E X16 slot. The first will not happen imo, so it's up to AMD whether they want to see Crossfire in x16, x16 mode on Intel platforms.

On the AMD side, there obviously are Crossfire boards that support x16, x16.

yeah, this card is supposed to beat the 320 and 640, and it clearly does, ATI is in the lead at this price point as of now, which is great, because now nvidia will make something better and cheaper, a la Adam Smith

Problem is that the price points don't really match up. The 2900 is priced a bit above the 8800GTS. This will put some downward pressure on the 8800GTS 640MB (isnt that one being pulled actually?), but not a whole lot. The 320MB version won't even drop in price.

yeah, what I meant was banking on the pull of the 640, then nVidia will be left with a huge gap between the 250-300 Price point and the 550-600 price point, I doubt they will let ATI rule that entire market. So the only feasible soulution is to drop the GTX, either that or introduce a new card at that price point which is highly illogical. Maybe I higher end car will be introduced and then the GTX will drop, thats what I have my money on
post #48 of 72
I don't even see how ATI could rule that market. Right now their 400$+ solution is a poor performer compared to Nvidia's 350$ solution, and in some cases even a poor performer compared to Nvidia's 250$ solution.

Until there is something to challenge the GTX in performance, Nvidia can ride the cash cow all the way home.

False. the 2900 beats out the 320 and 640

Lay it on me buddy. I've seen 20+ reviews that say otherwise.

Even if they tied in performance the HD 2900XT is still a loser. It puts off tons more heat, eats tons more power, etc.
