I currently have 2 22" monitors and want to add a third monitor or maybe HD TV in the middle. I have an SLI capable motherboard with a BFG 8800GTS 320mb. And they no longer sell this video card... So what options do I have to get a third monitor to work? Also if I wanted a fourth monitor (not going to happen, but just curious), would it work if I had 2 video cards? I'm not sure what the compatability is for SLI, does it have to be the same brand....etc...etc. Thanks in advance.
