GTX 980(s)

I started a thread about a psu over in the psu section but a gpu conversation started and i figured this was a better place to post it. I've heard quad sli gtx 980s have iffy scaling on 4k but is that the same if it were a 2650x1440 resolution? Or would I still have to lower the detail settings? (by the way the build wouldn't be used for gaming only. I'm planning on doing 3d rendering mostly so its not a huge deal but it's nice to know.)

Get three rog swifts. Quad 980 can easily drive it. I assume.

Iffy scaling = bad price/performance - So for the second card if you got an extra 80-90% extra performance, the third would get maybe 50-60% extra performance, for the same price. (These are guesstimate/rough number so take them with a grain of salt)

You'd be able to max out every game at 4k with four 980s unless the game is complete shit with SLI/doesn't support it. 1440p should be a joke for them.

Scaling has gotten a lot better than that from what I've seen lately, as long as you have a higher resolution to make use of the cards it seems like.

 

Take these benches for example, nearly perfect scaling to 4 way on multiple AAA games:

The best price to performance / bang is normally two-way sli, but games are slowly being more and more optimized for SLI, and in a lot of reviews 3 way configurations have -amazing- scaling at above 1080p resolutions(1440, 1600, 4k), Quad-sli is normally where for the times it works -right-, "omg 4k has 100 fps!) for the times it doesn't, "Well, I got an extra card sitting there getting hot, but damn is that sexy", so I think that when it comes to the 980's - threeway has the most / best results for right now.  Two way is the -literal- best(price and performance, yadda yadda), but three way you still get decent amounts of performance in a lot of situations, albeit not the best bang for your buck.  For 1440p use, tri-sli will keep your averages in the 90s to 100s or more of fps, which is good :3  Even if running at 60hz, that means it'll last a -good- long while.   Maybe two years of game releases without coming -close- to averaging at or near 60 / 70fps.
