i added a second 8800gtx to my rig not too long ago and i saw a nice increase in performance. more recently i added a third 8800gtx for 3-way sli, and i saw only a small increase.
i'm using 3dmark06 as a gauge. single card i was getting 12000's, 2 cards shot me up to 18000's, but with 3 i'm barely breaking 20000's (and that's only after overclocking as much as i can, otherwise i'm in the 19000's). am i doing something wrong?
i tried enabling physics, disabling it, and changing other performance settings, but that only seems to give me a lower score. is 3dmark06 not setup for more than 2 cards or something?
