If thesims you have do support it, then you must be doing something wrong (Its not turned on or your bridge is loose or something).

True about the memory.

Or you hit the cpu bottleneck on your way to complete use of the second card.

I'm not saying it doesn't work at all, I'm saying 'generally doesn't work' not really worth it. I had a couple of GTX9800 with a slightly oc'd quad core and generally with flight simulators, the bottleneck was the cpu...But with a single card too, with the exception of ROF (with the indicator).

Flight sims used to be heavier on the cpu side, that has changed now though, I admit. What gets me with this is that with a given price you get either 2 mid range cards or 1 really good one. About the same price as you do pay twice for memory.

And many games don't support it. Right now ROF and DCS that I'm aware of, with other flight sims, all you are left with is 1 mid-range card..
