The titan and the 780 ti seem to have similar stats when overclocked, and used titans are falling in price (sort of). From what Ive seen it seems like the 780 ti is better currently for running 4k. However on newer games that require more Vram, such as crysis 3 and heavy modded skyrim, it looks like the titan pulls ahead with its massive 6gb vram. So my question is, in the next 5 years, will the Titan be better to have, since it seems to do better with the newer games having so many textures and things that use Vram. Or is the 780ti gonna do better with its slight performance boost but half the Vram and worse "business processing" functions? Also which one do you think will retain its value better in terms of price?
