SLI GTX 970 FTW

I was wondering if anyone has SLI the Evga 970 FTW and how much of a performance gain is there?

performance depends on the games. around 50-60 percent better than one card. you want to test, take your current fps and multiply it by 1.6. that will give you a range

That about sums it up, however some games here and there may not support SLI. 

Anyhow, if not playing on anything higher than 1080p it seems like a waste to me.

I SLI'd the MSI 970s and depending on the game you can see 0% (Guild Wars 2, a total CPU bound game) to 80-90% (synthetic benchmarks) in performance.  Average testing will yield around 50-60% of what you currently get.

It scales a hell of a lot better than that for me.  I get about 1.8-1.9x scaling.  

 

You're running into some sort of CPU wall if you're only getting 60% scaling.

If you do more than 1080p gaming sure SLI is cool. But 1080 or Less you just waste money. I have 970 and every new game on ultra plays around 50 - 60 FPS which is the max, so you don't really need second card. + for second card you will need better PSU, about 850W one if you don't have one already. And remember to check if your motherboard supports SLI.
