According to:
http://www.techspot.com/review/283-geforce-gtx-400-vs-radeon-hd-5800/
Tested with the 257 vs 10.5 drivers. Fairly small selection of new and one or two year old titles. Using FRAPS to measure frames during "real" gameplay vs. results reported by timedemos.
The takeaway message is: for real gameplay the competing cards are completely indistinguishable. In the two cases where Fermi has a clear advantage the frame rates are too low to be playable in the first place, so at playable settings there is no practical difference.
Which means the difference in real world gameplay is more a factor of how big of an OC you get on your particular card.
Now, how could this happen? There a few theories:
1. NV has recalled all review sample cards and this testing was done with retail hardware. Retail card BIOSes may have been tweaked (read: made slower) so that retail cards are possible in the first place.
2. 257 driver is a showcase for optimization tradeoffs. In order to make a few commonly reviewed titles faster optimizations were made which decrease performance in other cases.
3. Testing fail
