So I'm a NVIDIA fan but I haven't seen anyone using NVIDIA for 3 displays. I want to build a new rig that can do 3 displays 1080p and possibly 3d. The most demanding game I play is battlefield 3. My budget for the build is 3000. I am recycling the power supply hard drives and ram from my current desktop. So what would be the best gpu setup? I was thinking 3x latest Amd video cards water cooled but this could be too expensive.
