MSI Radeon RX 570 8G OC $180 – $20 rebate – $30 gift card + $5 shipping at Newegg – use with Keras for machine learning $160

This is similar to the expired deal on the same card from Amazon. Slightly better if you do not pay tax at Newegg.

What convinced me to buy this card is that I found out that you can use non NVIDIA cards to accelerate machine learning with Keras quite seamlessly with plaidml. https://github.com/plaidml/plaidml
I tried plaidml last night on my GPU built into my i7 6700 (Intel® HD Graphics 530) which turned out to be just half the speed of the 4 cores/8 threads of the i7 6700 on my fairly deep stacked LSTM network. From the benchmarks it seems that RX 570 is about 10x faster than the Intel HD 530, so I hope it will be 2x faster than the i7 6700 for my Keras project. I think it also compares favorably with NVIDIA 1060, being about similar speed in benchmarks and having 8GB of memory instead of 3GB, for less money.
