I right now have a GTX 780 Ti (reference design and clocks). The main thing that attracts me to the GTX 980 is that it has more VRAM than the 780 Ti and it's cheaper than the GTX 780 Ti. I don't care about the little speed increase over the GTX 780 Ti, just the VRAM size. I want more VRAM. Already Watch Dogs uses more than 3 GB VRAM at ultra settings and the 2 latest consoles have 8 GB of unified RAM although of course not all 8 GB would be used as VRAM on the 2 latest consoles. At the very worst I would probably lose about $50 if I sell my GTX 780 Ti and buy the GTX 980, assuming their is no price drop on the GTX 780 Ti by the time I sell it.
