r600 will shoot nvidia's cards in the nuts. the 8900 bump is a bump.
At the rate AMD are going getting the bloody thing out of the door, R600 will be competing with G90, not G80.
As for 8900, you know what, I think that NVIDIA probably have a better idea than you or I do what they need to bring to the table to deal with R600. So 8900 "just a bump" might say something about R600. There's something weird about R600, something doesn't feel right.
youd think so right? IT has been a while with no benches or real stats about what the card will do. I am betting on the ati card though as the 7xxx series had terrible AA/af abilities and any x1800 or x1900 card seemed to crush them. the 8800 is a great card of course, but nvidia never makes a real all-in-wonder contender, so I am for ati in this respect only.....
I am not for anythign over 150 watts of power. what the hell???!!! I too wonder about the r600. I think however it will be the new standard. apparently ati doesnt care about showing it yet. I have a 620 watt corsair psu waiting in box for the new gpu. sad times.
I havent heard about the all-in-wonder card yet. I know its on its way. That will be a complicated card with all lamo crapped up m$ DRM in vista and vista's terrible sound support. Probably is a nightmare card to make with future proof certainty. 8900 is a bump, nothing particularly new about it but obviously it will be faster. this will make a 320mb 8800 GTS fall nicely into a near normal price range, something that is needed.
We, here on the sideline, can only take a guess at what marketing strategies come in handy. And we don't know what the R600 (from ATI's point of view) or the 8900 (from NVidia's point of view) is capable of.
Maybe the R600 is awesome (it will be). ATI might choose to wait until NVidia releases the 8900 before they let the R600 go.
Maybe the R600 has problems (yields, benches, whatever) and they try to solve this in the little time left (improbable).
Maybe the R600 is awesome but they still have problems in production capacity. They might choose to wait until it's widely available.
And maybe there is even another reason to hold back from ATI's stand. In the meantime though, everyone wanting to go for a DX10 card is going to buy NVidia. Something is going on, ATI knows this and it would be foolish to hold back while people are buying new cards for their Vista.
I don't have a crystal ball, but these people have studied marketing and business practices and plan their strategy. I am not putting any money on either card because I'd always lose. Both manufacturers have more info then I/we do.
Also, results accomplished in the past is no guarantee for the future, if NVidia booked bad results in AA/AF department as opposed to ATI, this doesn't mean it's still the same.
Unless this new material
has some benefits in the near future, I'm not willing to spend money on a power hungry piece of hardware. But then again, I always had NVidia cards...
620 W will be enough, way enough to power a system including the R600 though.
