That's pretty strange. I've used my 1.5GB per GPU GTX590 on my 57X10 rig at 4X AA and on my 25X16 rig at whatever AA I like.
As I recall, you don't even have a 25X16 monitor, and here you are, going on about the necessity of 2GB VRAM for your relatively low res needs.
The only way you need 3 cards or more than 1.5GB of VRAM is to run levels of AA that offer such minute gains no one else really bothers with them. Your rig is as unbalanced as you are- you settle for no surround, no 3d, no physx, no 25X16, and run tri-fire for pointless AA levels.
