I've posted a build in the Systems forum that seems like it will work well, but before I was about to buy it I grew concerned that the one 780 Ti I was purchasing for the system would not be enough to hook up all three of my monitors.

I have three 2560x1440 Dell 2713HM Monitors, which have DVI-D and DisplayPort connections. The specs on the 780 Ti read:

One DVI-D Port: 1st Monitor
One DisplayPort: 2nd Monitor
One Dual-Link DVI-I Port: ?????

I thought that you needed DVI-D to run at 2560x1440, but this card has one Dual-Link DVI-I instead of a second DVI-D, which is confusing because I thought DVI-I was the lesser of the two and would not work at 2560x1440, but what is DUAL-LINK DVI-I?

For reference, the R9 290X has TWO DVI-D ports listed, instead of what the 780 Ti has.

Can someone explain in more detail if this card will work to run all three of my monitors on one card? I recognize it won't let me game on all 3 at once, but I want to be able to game on 1 monitor at full settings and just have browser windows and other programs open on the other two.

DVI-D only carries a digital signal, while DVI-I has digital and analog(so you can use a dvi to vga adapter). Both ports come in single link and dual link versions. Dual link is needed for larger resolutions like 2560x1440 and for higher refresh rates like the 120Hz and 144Hz monitors. Your 3rd monitor should work just fine in the DVI-I port.

Great, thank you! So you are saying that with the ports available on the single 780 Ti, I should be able to hook up all three monitors at 2560x1440 correct? I can use the Dual Link DVI-I, the DVI-D, and the DisplayPort to hook up a total of 3 on one card?

To me you won't see any different from the DVI-I it is almost the same the cable will hook up to the monitor as long as you got a DVI cable without the + in the male jack of the cable. DVI-I have a - at the end of the cable. I haven't notice any different when I hook up to t DVI-D port.
You can get a HDMI to DVI-D. And tbh when I strip the cable down to see if wire was really hook up the HDMI as a full digital link for the DVI-D. It doesn't really need the extra ground into the + into the DVI-D. Plus you won't get any sound from the HDMI to the DVI-D or DVI-I.
