I'm new to computer building so I come to you all in hopes that I could be steered in the proper direction. Currently I have an i7-3770K at 4.4Ghz, EVGA GTX680 FTW+ 4GB, ASUS Z77-V Deluxe motherboard and a Corsair 750W power supply. I have a 27" iMac as my primary computer that I run a display port to mini display port cable from the GTX680 to the iMac for use as a monitor with the gaming computer and this works out great.

 

Now I would like to move to a triple monitor setup for the wrap around 3D cockpits. I play FSX, DCS and X-Plane 10. The iMac's screen is a glossy backlit LED with 2560x1440 pixels. Am I correct in assuming it would be best to find two other monitors with those exact specifications? I've been looking at the QNIX QX2710 Evolution II monitors. 

 

What are some of the things I should expect to do for accomplishing this setup. I understand that with NVIDIA I would need to use Surround. How about connections for the new monitors from the GPU? As stated above, my GTX680 is currently using it's 1x Displayport connection for the iMac, but also has 2x DVI available and 1x HDMI. I know there are a lot of factors that can effect my next question but what are the "average" FPS losses generated from going from 1 monitor to three?

 

Any advice, tips, pros, cons, cause and effects anyone could provide would be very helpful!

So I feel stupid.. Just throwing that one out there because if I would have READ the top of this forum and saw this http://forum.avsim.net/topic/407743-how-to-setup-3-monitors/ PINNED to the top of the page I probably would have not needed to start this thread.
