I will be going with either two of these or two other Fury models (either the non X or the Pro).
I don't want to spend more than £300 per card, but, if the Fury comes in at around £400 it won't be long before Nvidia slash prices on the now venerable 970 and 980 and the price of the Fury tumbles also.
But I run 4k, and tbh? I wouldn't even consider this card at any lower. It wasn't designed, built, or had drivers made for it to run any lower. The resolution is why the HBM is on there, etc.
I looked at a review the other day and the Fury X is 2% slower overall than the 980ti at 4k. That's why Fury X has one quite a few awards and generally went down well (unless you were daft and thought it would trounce the Titan X and thus disappointed and whiny about it...).
