What satisfactory solutions are there to achieve three monitors on Ubuntu? I know some ATI cards (Eyefinity) can support 3 monitors from a single card, but I don't know how well this is supported under Linux and besides, I've never had much luck with ATI on Linux.

The alternative is to try two cards, but there seem to be problems there too. It looks to me like xrandr cannot support 2 GPUs. I believe you'll end up with two separate "Screens" across which you cannot move applications or windows, unless you enable Xinerama which as I understand it disables some acceleration and probably compositing too.

I've found so much conflicting information on this online, I'm really confused. Please advise!
