From reviews we see that 8800GTX and especially GTS suffer from 2560x1600 resolution. The fps hit is very big, bigger than X1950XTX. What causes this strange hit on G80?

From all that I have read the 8800GTX is still an absolute beast at 2560x1600.

Yeh, but X1950XTX is very near to 8800GTS.

Not really IMO, right now i believe the 8800's are being held back by drivers. Wait for the new drivers to come around and see what happens.
 
Nvidia just released new drivers that support the 8800. Sure they aren't really optimized for it, but nonetheless they are new drivers. Unfortunately, my X1950XTX was shipped 4 hours before the 8800GTS was in stock, otherwise i would have gotten a 8800GTS instead.
 
Well if you go back and look at the reviews you will see that the quality settings are lower on the x1900xtx vs the 8800gts. So yes like in the [H] review the x1900xtx has a few higher frames rates than the 8800gts but the quality of image that it is rendering is lower. I have yet to see a review where they ran the x1900xtx at the same quality settings at 2560 x 1600 that they are running on the 8800gts
 
At a ultra high resolution like 2560x1600 graphics cards are very much memory bandwidth limited. Although the 8800 GTX leaps and bounds ahead in categories like texture fillrate and pixel processing power, it doesn't beat out the x1950 xtx by as much when memory bandwidth, it has the 384-bit bus, but it is also using slower GDDR3. It still has more memory bandwidth than a x1950xtx it just doesn't beat it by as much as it does other stuff when it comes to memory bandwidth.
 
Most of the reviews I read said they only suffered if you cranked AA, but they still smoke the ATI in general in that res if you look at the 10 or so reviews out there.
