I have them mounted in the X58 MB for tomorrow nights FSO. I have tried a couple of games at 7680x1600 2xAA 4xAF without issue. I prefer just one monitor for AH which is what I intend for FSO. I ran two tests with these cards. The first test was on a Socket 775 system with the Q9650 MB and using 3D Mark 11 I got something in the P8000 range. The second test with the X58 system and an i7 975 Extreme hit into the P9600 range. I understand the Sandy Bridge systems are hitting into the P15000 range so I am anxious to see that MB arrive! These were just quick tests without a lot of tweaking.
The best side is the internal case temperatures are way down and noise levels are nonexistant but obviously thats not worth the cost involved.
