R9 280 for about $170 to $180 range
R9 285 exactly in the $200 range (updated forgot about this card)
R9 290 for about $240 ish (R9 280x is around the same price, but the 290 is much better)
If you want Nvidia then you can get the GTX 960
GTX 960 is for about $200ish for the 2GB and $230ish for the 4GB.
But the 280 offers similar performance for cheaper, the 285 outperforms it for the same price and the 290 outperforms the 4gb model (performs about the same as the 970). But the GTX 960 is more energy efficient.
