I have recently acquired a third LCD and want to extend my existing dual-head desktop onto it. My current graphics card (ATi x1900GT) is unable to drive more than two monitors at once and it also is getting a bit long in the tooth, so I will be replacing it. I haven't run more than two displays at once, so I am wondering what's the best way to go about this. My motherboard can run two GPUs if needed as it has two PCIe x16 slots (NF4 SLi chipset.) The CPU isn't all that fast, so anything more then a midrange card will be useless in my system. Here's what I was considering:
1. Radeon HD 5750, as I can connect all three displays to the same card. I just don't know if that is supported at the moment with the fglrx drivers, since my x1900GT has been using the Xorg Radeon drivers for some time and I've fallen out of the loop with what's supported by fglrx.
2. Two midrange NVIDIA GPUs like the GT 240/9600 GT with the three displays spanned across the two cards. I do like the fact that the NVIDIA cards do CUDA and VDPAU video playback, but I don't know if the NVIDIA drivers can support spanning a desktop across multiple GPUs.
If I'm way off in left field here, please say so.
