I right now have a GTX 780Ti and was thinking about upgrading to a 390x or a 980Ti and selling my 780Ti. The only reason I'm considering a 390x is because of the 8GB VRAM on the 390x even though it's slower then the 980Ti. Xbox One and PS4 have 8GB shared RAM and some PC games already can use more than 3GB VRAM if graphics are maxed out at 1080p or higher res, for example GTA V and Watch Dogs. I want a card with at least 8GB VRAM and my only choices right now are a Titan X, 390, and 390x, but Titan X I can't afford even after selling my 780Ti.
