My examples- GTX 770, 780 and perhaps the 980 for NVidia. AMD: R9 295X2, maybe the r9 270 since you can the 750 ti for $100 bucks a lot of the time. (That's cheap for a card that can play BF4 onn ultra at about 45-50 fps on ultra)
The 770 really needs to be cheaper. Even the cheapest one i've found the pny 3 fan version is still $300. With the 970s starting at $329. there is no reason for this card to still be this much.
