Hi folkes

I do have a feeling that one of my two graphic cards has a problem. I do not know what causes the following: When I tested the cards in benchmarking, I got the same score with just one card installed in the machine as I got with both cards in sli. But when I switched the slotts of the two cards: the first card in slott two and card 2 i my main slott, then the benchmark score doubled.
I have two identical cards, and both the slots are PCI 16X.

Do you have any idea about what might cause this results?
