I would go with 2x 980 becuase of the heat output of the 390x's

For 4k and 1440p the 390x's would be my vote.

1080p 980s

SLI 980. When single card is working the 980 outperform 390X. Here is the proof.

Keep in mind that CF is more efficient than SLI - CF can get up to 99%...

That's a bit like asking a Porsche or a Lamborgini what performs better at the 100km/h speed limit? The Lambo of course but it doesn't fucking matters at that speed: it doesn't matters at 1080p both set ups are exceedingly capable and even overkill at that resolution

 

So do get SLI or Crossfire only if you plan on 4k. And it should be close but slight edge on the 980 on some games, that might change with DX12 games but we're not sure until they're out.

390X no question.

A 1000 watt would be optimal.

This power supply is built by superflower

It's a tier two psu with a *5 year warranty, I'm also thinking about doing a crossfire and this is the psu I'd go with.

"" At 4k?

For 1080p a single 390 (non x)

 

For 1440p CF 390 (non x) or single 980Ti

 

For 4k CF 390 or SLi 980Ti

 

 

I just cant justify the price of 980's vs the other options, same as the 390x's, CF 390 will out perform the 980's at 1440p+ and cost less, the difference in performance compared to the CF 390x's is very small and the price difference is rather big.

 

Just my opinion.
