290 is a excellent option for $200,even used.Nothing comes close period.God Pascal can't come along soon enough so we can finally have something finally a lot more for $200.
You have chosen wisely.
I think your best bet for getting 290 levels of performance for $200 after Pascal and Polaris ship will be to buy a 290.
This is most likely true,still some people refuse to buy used.
It is riskier for AMD stuff. You don't know if it was mined to death.
