Well, after about 11 total hours of numerous boots and reboots, installs/uninstalls, driver downloads after driver downloads, tweaking this and tweaking that in the "Display" options, pulling out, and putting back in the cards, half a bottle of excedrin and a few kicks to the dog...I got it to work. 4 freeking monitors off of 2 cards...WHEW! What a pain in the ass.
Customer support for Dell, ATI, and Maddog (I didn't even bother with Softee) will have nothing to do with anything more than 2 monitors...screw'em all.
From what I gather, ATI software couldn't distinguish between both cards, so I ended up doing a step by step install hardware>software>drivers for each card individually. S.O.P. right? Well what nobody tells you is that you have to open up the Device Manager and actually separate (click/highlight) the two cards and download (update) drivers for each one at the same time then re-boot. Even though both cards are identical, they will both have different assignment numbers beside them.
So what have I learned?
* I'll stick with nVidia, never had a single problem with them
* I wouldn't buy identical cards again, I think with 2 different cards (from the same family), your system would have an easier time distinguishing the two...maybe.
* When I began, I installed both cards at the same time. I don't think that was a good idea...one step at a time.

And by the way, the colors suck, everything's a little dingy no matter how much I messed with the controls on both the monitors and the card's software. What a nightmare.
