What are my options for running all 3 monitors? A new AGP card with 3 outputs (do they make these?)? A PCI card that is compatible with my AGP card (Invidia GeForce 5500)? One of those adapters that lets you run two monitors off of one output (I think I saw one of these before)? I used to have two 17" LCDs but I just picked up a 22" LCD on sale so now I have one of my 17" LCDs sitting on the floor.
