I am currently considering a new iMac, but I was wondering if this would be able to support two extra monitors.

The setup I am considering:

  • iMac built-in 27" monitor.
  • Current Dell 27" monitor @ 2650x1440 (Dual-link DVI via adapter)
  • One of the Thunderbolt displays @ 2560x1440 (via one of the two thunderbolt ports)

This is really two related questions:

  • Is the above setup viable at all?
  • Will the available resolution be restricted by the video card?

Yes, it can. Here is an example of a 27" iMac with two 30" Dell displays.
