I am making a computer for work and need to hook up 6 4k monitors. I am going with a GTX 980 SLI. My question is will 2 GTX 980 SLI work for connecting 6 monitors or will I need 3 in SLI?
Sli is limited to 4 monitors. It doesn't matter how many cards in sli, it's still 4. Not in sli and adding more cards will let you use more monitors. A 980 supports 4 monitors so you can do just 2 but what work are you doing that needs 980?
