From my old computer, I have a spare HD-7770 2GD5 Graphics Card that's just sitting on my shelf. I'm running 2 monitors right now and thinking of adding a third. My first question is this: will this computer be able to handle a third monitor (assuming all 3 are 4k monitors), and would it benifit me in any way if I install this extra GPU into the computer? (can the power supply handle it? Are Nvidia and AMD cards not compatible together?)

Any help you can throw my way would be great. Thanks in advance!
 
Solution
Your GPU can handle 3 monitors, even 4K, as long as you don't try to play games on more then one. Adding this AMD card is pointless, and your PSU, while good, would have problem powering them both.
