The 285 is around $150 and edges the 960 by about 3%... the 960 will overclock about 18% to the 285's 16%
The 960 runs $180 - $220 but figure $210 - $220 for the higher clocked models....Almost all the 380's are < $200. Between the two, the 380 is faster.
If ya have to pick a "shining star" in AMDs current lineup, it would have to be the 380.
