Thanks đàm!
For those of you finding this thread in the future: I found the following blog post 85 on GPU selection. TL;DR Don’t cheap out like I wanted to - invest in a card that’s suitable for the job. Convolution operators are performed using cuDNN, so it makes sense to require compute capacity 3+, and since Kepler cards are allegedly quite slow you’ll be looking at Maxwell or more recent cards.
And of course you can be my friend đàm!
