Does GTX 980 support SLI?
The NVIDIA GeForce GTX 980 SLI option is one of the best setups you can buy today, with huge performance scaling in most games, and not that much power consumption. Consuming only 430W in total, the GTX 980 SLI system is a great alternative to a Radeon R9 290X setup in terms of power consumption and heat output alone.
How good is 980ti SLI?
We can confidently say that a 980 Ti SLI setup running a supported game is definitely no slouch. Both cards deliver a constant 4K 60FPS experience. In the two situations that it didn’t we could easily turn down a few settings to reach the 4K 60FPS target.
