I recently purchased the Asus gtx770 card and a Dell U2413 monitor to go along with two previously purchased U2410. I have tried to do some research and right now am planning on displayport on the U2413 and of course hdmi on one of the other monitors. Which is the best connection option for the third monitor? HDMI to DVI connector?, Displayport to DVI connector? Straight DVI? Thanks for the opinions in advance
