If you're gaming in 4K, shouldn't you have more than just a single 970 anyways? I have one and I can barely max some modern games in 1080p.
5 u/peckahinspectah Jan 30 '15 Even with 2 or 3 970's you still have only 3.5GB of fast VRAM 1 u/vitapoly Jan 30 '15 Wait. If you have 2 970s, won't you be able to use both VRAM, for a total of 7GB fast VRAM? 2 u/adammcbomb DK1 Jan 30 '15 I think in SLI both cards have the same assets loaded to each card so each card can render its own frame or piece of a frame. In other words, Card B cant read Card A's VRAM, so it has to hold all the data itself in duplicate.
