Right now, I'm benchmarking two GIGABYTE GeForce GTX 1080 G1 Gaming video cards in SLI, and I went online with a 1.5-hour Facebook Live video when I installed the second GTX 1080 G1 Gaming card. Check out my FB Live stream below!

I've been playing with the two GIGABYTE GeForce GTX 1080 G1 Gaming cards in SLI for a few hours more now, and I've been pushing some hard benchmarks at them. With both cards hitting 98-100% scaling, our entire Core i7-5960X powered system consumed just 490W total. We've put the cards through their paces with some great results, and now I'm overclocking the cards and they're handling over 2GHz on the GPU, even with its single 8-pin PCIe power connector.

The Titan X uses 315W, while the HBM1-powered Radeon R9 Fury X uses 300W.
