Re: [PLUG] 3 MOnitor Video Hardware

There's a lot of outdated info here. Three (or more) DP outputs is actually the default in current mid-range and high end consumer/gamer GPUs. It went this way with the late editions of the GTX 960/970 and is spreading down the lineups as DP monitors become more common. This is because DP ports are actually cheaper than HDMI/DVI for modern GPUs. That said, even in the Pro lineups, you’ll need to be careful to check specs, as a DP doesn’t intrinsically mean 4K support.

Also, unless you need multiple monitors being treated as a single physical display, or you are planning to mix different GPU vendors, multi-card multi-monitor solutions are perfectly valid and generally not any harder to configure/use than a single-card multi-monitor setup.

DisplayPort.  It's no contest.

"Drives three 4k monitors" as a "must have" makes it pretty easy to answer the rest of the question:

Intel GPUs can drive three displays, but I don't know of a single mobo that has three DP outputs; there aren't even many with two.  Consumer (read: gamer) oriented AMD and nVidia cards typically have one DP output, and very few have two.  So for three DP outputs, you're pretty much limited to professional graphics boards: nVidia's Quadro and NVS lines, AMD's Radeon Pro (or older FirePro) series, or something uncommon like a Matrox C680.  My recommendation is an AMD FirePro W4100 or NVS 510, both of which are about $250.

If your mobo has two 16× PCIe slots, then it might seem like a cheap solution would be to buy two cards, each with dual DP outputs.  But my experience with Xinerama back before cards had multiple (independent) outputs was that this setup was always finicky.  Googling "how to set up three monitors in X" suggests that things haven't improved.
