Yes, but note in the video that the resolutions were all high. You will have no problems if you're gaming at 1440p or lower.
Also to note is what happens when DirectX 12 comes out especially if you can do an sli setup. Currently the VRAM on sli does not stack. So, my 970 setup still only uses 3.5 gigs even though I have 7 GB available. With DirectX 12 the VRAM on sli setups will STACK. Which means I will have 7 GB of VRAM. More than enough. Star Citizen confirmed they will support DirectX 12.
2 970's is a killer set up for a bargain price. Way better value than 980's imo.
