TBH the 980ti is still better than the Fury X even at 4k. Thanks to certain devs. THen again it is only the rare game.
Would have thought it may have had something to do with HBM for the extra performance at higher res along with some more refined drivers from AMD.
384 seems a bit meh especially for 6GB. I guess its better than 256 for the 4GB.
Kind of funny really. Just like how the 7970 came such a long way thanks to more mature drivers. Just look at where the 290x can get you now.
