I have an AMD A10-5800k. I love it. The motherboard is FM2-A75IA-E53, which on MSI's website claims it can utilize "dual graphics" (or crossfire for APU's).

If I hook up a discrete graphics card to my PCI-E slot, what is the maximum amount of monitors I'll be able to hook up [while utilizing "dual-graphics"]. Just the two on the discrete card? All three on the discrete card? 2 from discrete, and 2 from mobo?

Looking to get a triple monitor setup going, but I'm on a Mini-ITX, so 2 discrete's in crossfire isn't an option.

You can't use both the integrated GPU and a PCI/PCIe GPU at the same time because the integrated GPU is automatically disabled when a PCI/PCIe GPU is detected. This is necessary to avoid a resource conflict between the two.

So the number of monitors you can use simultaneously will be dictated solely by the capability of whatever GPU model you install, full details of which can be found on that GPU manufacturer's website.

Without Crossfire you will be restricted to two monitors unless you buy a triple-head card instead of a twin-head. That's serious money.

I ended up getting a Radeon 7770, as it supports Eyeinfinity on a single card. I also ordered an Active Displayport adapter (to HDMI) so I can use all 3 monitors. Thanks for the advice!

Gee, Phil...

I just bought an ASUS Z87-A motherboard. There is a BIOS setting: iGPU multi-monitor, enable or disable.

The explanation on it reads:
"enabled - empower BOTH integrated and discrete graphics for multi-monitor output. iGPU shared system memory size will be fixed at 64M."

This leads me to believe that both integrated and discrete graphics can be run concurrently, in contradiction to your comment. What do you think?
