Quite obviously the only GTX 260 cards available now are 216 shader cards. One thing that surprised me is both cards run at their own factory clocks, which I had previously thought the clocks would be the same in SLI.
This means, that because my FTW edition card is actually faster than my new 260, I get near 100% scaling in almost all situations:
All Done @ 1920x1200
COD4: 2xAA, 16xAF
1 card: 63.8fps
1 card: 94.5fps
Oblivion: 16xQ TSAA, 16xAF
SLI: Avg: 65.390 - Min: 38 - Max: 114
1 card: Avg: 33.515 - Min: 20 - Max: 58
Far Cry 2: 4xAA, 16xAF
* Average Framerate: 82.58
* Max. Framerate: 117.15
* Min. Framerate: 64.82
* Average Framerate: 44.43
* Max. Framerate: 63.07
* Min. Framerate: 35.19
your minimum frame rates are concerning with a single card. i get no less then 55 fps @ 2048x1152 with 4xAA 16xAF. that goes for cod 4, 5 and 6. never ever seen them go below 50fps. i thought about adding another 260 myself and decided not too because my frame rates are still very good ...
