My son recently got a 27" 2560x1440 monitor with dual dvi input. He would also like to use his 22" 1080p monitor as a second monitor. He does game heavily (FPS). Is there a video card that will drive both monitors?
Any video card that has dual outputs (most do) will work for simply adding a second monitor. Just plug it in, go to your desktop settings and configure how you want the second monitor to be used. Running 2 monitors does not increase the load on a video card.
