I need to spec out a PC for our conference room. Most likely going with an i5 Haswell as the CPU. We have two 70 inch 1080p monitors on the wall, and the boss wants to have two 24 inch monitors at the podium for running presentations. My initial though was to run the two 24in monitors off of the IGP, and the two external monitors off of something like an HD7770. Would this work?
