So recently I bought myself a 4k monitor for a good price. But currently I am running a Gtx 980 with a i7 4790k and 16gb of ram and doesn't feel to be enough for 4k gaming.
I am wanting to upgrade my gpu so I can do so. But my problem is, I am not sure if I should get a second 980 and just run sli or return my 980 and get 2 cards for crossfire. rx 390x seem to be going for cheap as of now and that was what I was looking at get 2 of for crossfire. But at this point in time I amade not sure what I should do.
What are your guys suggestions?

The 1080 is a bit out of my price range, wold be adding around an extra 250 to 300 if I were to cm exchange my 980. Problem with running sli is my motherboard doesn't know support sli and I am having trouble finding one. computer shops in my area no longer supply sli compatible boards. If I were to crossfire 390x I am only going to have to add an extra $100 on top of that. But I am still not sure if the CF 390x is the way to go

Ok, you said return 980, which means return for full price I'd assume. If it's not in that case, you could try a 1070 which also can play 4k at lower settings.

I'm not understanding. You say: "problem with running sli is my motherboard doesn't know support sli and I am having trouble finding one"
Are you trying to get a new motherboard for SLI, or are you just saying it doesn't work on your motherboard?

My bad, I meant motherboard doesnt support sli. Not sure why I added the know in.
Yes I meant return the 980 for full price.
So the cheapest 1080 I can get is $860.
But one r9 390x is $330 so I can get 2 for $660 which will be $200 cheaper.

I don't want to grab at attention here, but select a "best answer" for other people who might have the same question. These posts are referenced in google searches, and you might save someone else a headache of a time researching!

That is an LGA 1150 motherboard. The PCIe x16 slot that is closest to the CPU (the one you put your graphics card in) is always direct PCIe lanes to the CPU (rather than through the chipset), and all LGA 1150 CPUs have PCIe 3.0. Also, not sure what "two cards" you're referring to, but none of the cards mentioned in this thread are PCIe 2.0; they're all 3.0.

The 2nd PCIe x16 slot is only electrically x4, and it's PCIe 2.0. So that's effectively PCIe 3.0 x2. This would reduce the performance of a 2nd card. I would not recommend crossfiring with that mobo.
