If you want to get one to play with... sure, go for it. If you dont like it, you can probably flip it and get most of your money back. But from a mining ROI standpoint, you know its not going to be worth it. Even if it does 2k CN, I could buy 8 RX 5xx (used) for the price of 1 chip and get 6-7k hash pretty easily.
not using under 250 watts

But I did decide to buy the taichi x399 from newegg today it will allow the 1950x or the new beast 2990wx.
I got multiple promos on the mobo
319 + 20 tax = 339 - 25 pay with master pass = 314 - 40 rebate = 274 - 50 dollar gift card promo = 224 -3 = 221 which is
cheap for that board.
