The GTX 770 and R9 280X tend to trade blows depending on which game it is :

For Bitcoin mining, AMD cards have always been king in that domain, but nowdays specialized companies have made ASIC mining cards that consume less power and mine many times faster.
The R9 280X seems to be the best choice here.
