Finally have done some checking of Sli gpu usage with CoD. Both cards are running within 1% of each other (98---97%) and once up to running temps within 1deg C of eachother (about 58---59deg C). Have made up my own profile as follows, try it for yourselves to see if it works for you.

"Nvidia Inspector" settings.

Sli compatibility bits (Dx10) 0x00000003
Sli compatibility bits 0x00000003

Anti-aa SliAA AA_MODE_SELECTOR_SLIAA_DISABLED
SLI_GPU_COUNT_TWO
SLI_PREDEFINED_GPU_COUNT_DX10_TWO
SLI_PREDEFINED_GPU_COUNT_TWO
SLI_PREDEFINED_MODE_DX10_FORCE_AFR
SLI_PREDEFINED_MODE_FORCE_AFR
SLI_RENDERING_MODE_FORCE_AFR

I also run EVGA "Precision" and syncronise both gpu's to the same clocks (stock)

System Specs : -

AMD M4N98TD-EVO (980a Nvidia chip)
AMD 965x4 @3.4g (Stock)
8 gig 1333 ram
700w Cooler Master Sli PS
1Tb HDD (Partitioned x 5)
2 x GTS 450 in Sli. (one EVGA, one Asus)

I am getting fps over land, cockpit "on" (London Raid) 45--60 depending on AA fire and exploding He 111's. All settings on "High" except for "Buildings Detail and Forests" which are "Medium".
There are still some micro stutters at times but I can't blame Sli alone for that as it was also happening with a single card. The reason I am not running 2 EVGA's is that I couldn't get a second one here in NZ when I decided to go Sli, but being able to sync both cards to the same clocks is great.
