I am just about to order a second 17" TFT to match my existing one, I noticed where I was doing some DVD Authoring last week that I need more screen estate.
I would like to stay with Nvidia cards if at all possible, partly because I need good hardware 3D on at least one screen and partly because I know where I can grab a really good dualhead Nvidia card really cheap.
Replying to the list this time.... D'OH !
I can't help much as I use ATI cards, but dual headed supports comes in various forms.
With ATI drivers I choose to have "one big frame buffer" that covers both monitors and runs with one window manager. Hardware acceleration (I use openGL) works on both monitors (as there is only one frame buffer).
Alternatives provide a frame buffer for each monitor, which can be used independently (2x window managers) or together with xinerama, but I would guess anything in the driver is going to be more efficient than xinerama at putting them together. BUT xinerama may be able to put more than just two together.
I'll be trying to put 2x ATI X800s in a box soon (quad headed!)
