3 Monitors Won't Work Windows 10

[VeNoMxKinG]

I have 2 Asus 1920x1080 monitors. One connected with DVI Dual Link and one connected with HDMI. I also have a Dell 1920x1200 monitor connected with DVI Single Link and the dell monitor will not work unless I disable one other monitor.

PC Specs
GPU - R9 280
CPU - FX 8350
Mobo - M5A78L-M USB 3

If I can also use the mobo graphics for the dell monitor that would be fine as long as it doesn't effect my gaming on my 144hz monitor.

Did it work before W10? Most cards will require you to use a display port output for the third and later monitors.
