wow one card that bad ? seems pretty odd.

the reason the other games were running is because they were not even using SLI, they were using the onie card that runs good.
and on the occassion when it maybe did do something with the bad card it crashed.

thats how i see it.

the whole SLI thing is nothing but a joke. they have never gotten it to work properly and games and game programmers just do not care about SLI because its such an expensive thing for the average game player to have to afford.

in reality sli will increase your performance but in truth you wont see huge gains, atleast the way i see it, until you are at 1900x1200 or higher, thats where the dual cards really start to show their power.

yes you get improvements on the lower graphics but not like a higher resolution.

RMA that bad card tommorrow if you still have warranty
