I have one monitor taking up the HDMI port, but now I want to run dual monitors and can't seem to find the right buy. I think I need something that will hook up either to my DVI single displayport, or one of my Mini DisplayPorts. I also game a lot on my computer, and I'd to be able run my games well (About 80 FPS) on both of my monitors. I have $150 to spend, maybe more. Please help me out with finding the best I can for the price, I'm a little lost.
