Yeah, it's a shame, but at least the performance increase would never be that high anyway, even if it could hit what everyone else was hitting. It just would have been nice to get an extra 5 frames in GTA V, which is pretty much the only game I'm interested in that needs it. I can't get anywhere near max settings in GTA V at 1440p. With everything at the max settings, it's one of the most demanding games to play. An overclocked 980ti struggles to get consistent 60 FPS at 1080p, but that's usually over grassy areas. With a few unnecessary settings turned down, I can hit 70-80 FPS most of the time, with 55-65 being my range when in demanding areas/situations.
I have been tempted by XFire Fury, but it's not happening. I think I can be happy with the performance until Arctic Islands. Besides, the last two games released that I'm interested in—Phantom Pain and Mad Max—are really easy to run and work well with AMD and nVidia at 1440p. Tomb Raider, SoM, Splinter Cell Blacklist, Bioshock Infinite, Mass Effect 3, Mad Max, Metal Gear Solid, Dishonoured, Borderlands 2, Arkham Origins, AC Black Flag, Far Cry 4, Hitman Absolution, Just Cause 2, Mafia II, PAYDAY 2, Sniper Elite, BF3/4, Call of Duty, Watch Dogs, The Witcher 2. So many games I haven't played yet that run fine at 1440p with a Fury. The only exceptions are GTA V, The Witcher 3, Wolfenstein, AC Unity, and Crysis 3, four of which are regarded to be the most demanding video games available, irrelevant of what GPU you have.
