Nvidia preparing faster 9800 GTX drivers
The reasoning behind this is apparently due to AMD’s HD 4850 performing too close to the 9800 GTX.
We know that this performance jump will affect 9800GTX, but as its G92-based card the new driver might speed up some other G92-based products.
Nvidia is doing this simply, as with current drivers Radeon 4850 and 4870 are getting too close to 9800GTX performance and Nvidia wants to make a stand.
The performance might be so good that internally Nvidia calls it 9800GTX+. If we see some big improvements that will clearly mean that Nvidia was holding some performance potential back and that it was waiting for the new ATI card.
