yes you will be able to run up to 4 monitors with this card either through 2 dvi ports or HDMI and DVI.
What would this be able of? http://uk.pcpartpicker.com/part/evga-video-card-03gp42669kr
You can actually go to the website for these cards and get the manual. I believe that card runs up to THREE monitors but I don't know the combination. Likely:
a) 2xDVI + HDMI, or
b) 2xDVI + Displayport, or
c) 1xDVI + VGA (adapter) + HDMI, or
d) 1xDVI + VGA (adapter) + Displayport...
I wouldn't pay extra for a 3GB GTX660 either. Probably better to get something more like a GTX770 with 2GB depending on the cost. Most GTX660's are 2GB but they have more expensive 3GB versions that don't benefit.
