580...works almost as well as the 590, its cheaper, and if u buy another 1 in the future for sli itll work twice as good as the 590 (which is built in sli)
definitely ignore the dell and the eizo...i think your best bet is the zr24w. Go to newegg.com to look for cheaper ones as well.
If you plan to game in 3d your monitor has to be 120Hz, ~all of those are 60.
Good luck with your build and ask if you need more help
