No need bait like that. (goes for both)
It does fine for 4k. If you don't overclock it's not far off the reference 980 ti, basically trading blows.
Small form factor.
Sure it's not the best option, but it's not a horrible card either like you try to imply.
No,it's not a horrible card at all. If I was running 4K resolution I think I just might go for it over the Ti. Reasons being it's a pretty close race as it sits right now. I assume it will get somewhat better on more mature drivers. I'd have to think there would be voltage tools available soon. Knowing I wouldn't run either of these cards at 4K solo, if I assume this behaves as the 290s did, Crossfire scaled a bit better than SLi, so it's got that going for it as well. The reasons I might not include AMD's typically slower support for new games and Crossfire profiles, GamedontWerks©, and the 980's already known strong overclocking potential.
