I currently have a GTX460 and I love it. I am not ready to upgrade my GPU at this point, but I am thinking about running a three monitor setup. This would have two horizontal monitors for editing my videos like I have now, and a third veritcal monitor for screenwriting (I want to be able to see the entire length of the page). Is it possible to run the two horizontal monitors off the GTX460 and the third off of a cheap graphics card, or do GPUs have to be set up in crossfire (or whatever they call it now) when you run more than one. I always thought it was the latter, but I am looking for a way to avoid upgrading.
