Recently picked up two GTX 460's and I am running them in SLI mode together. However, I am not getting very good framerates. The game I play is BF3, my framerates hang around 20% on ultra . Which is quite a bit less than expected. This is my first SLI rig and I am not sure if I did everything right, I have SLI enabled in Nvidia control panel and have installed the 285.62 Drivers. Do i need anything else? Also, when I run a GPU stress test I have It says my second GPU is only running at like 30%?

2 GTX 460's in SLI - (One is made by Zotac, the other by PNY. They are the same size memory, clock speeds, and everything else. Perhaps the BIOS image on the cards has to match exactly?)
