A discrete GPU crunches the most, somthing like a GTX1050 costs ~ $120 to $150. |

For reference, here's my RPi2. A RPi3 should do better. https://setiathome.berkeley.edu/show_host_detail.php?hostid=8202849 |

First remember that a GPU is useless without a PC host whereas a pi is a complete if rather slow computer. Assuming you have a PC to host the GPU then I would look at the nvidia family not the AMD family as the nvidia offerings appear to perform better and require less effort to get crunching than the AMD offerings at the same price point. So which group of the nvidia range to look at? Nothing older than 7xx is worth considering as they are now well below the power/performance curve. Of the 7xx only the 750(to) are worth looking at, but they are now at, if not beyond, their production life. Which leaves us with the 9xx and 10xx sets. The 1050 and 1060 are getting good reports for price/performance. But it really comes down to how much you want to spend in terms of both capital and running (energy).

A GTX1030 will be better than just a CPU, but not significantly. Others have already suggested a GTX1050. A lot of folks have found that the big step in performance between the x30 and the x50 GPUs to be well worth the extra spend. On paper the performance of the 1050 should be more than double, if not treble that of a 1030 for about 20% extra.
