What hardware setup are you using for deep learning? • /r/MachineLearning

I just started on a project that is doing deep conv nets over a fairly large data set (73x144x1 images for now, once I have the basic pipeline setup up I want to train it on 146x288x10 "images", and I have a couple hundred thousand of them). I'm currently using TensorFlow on my 2011 MacBook Air to build out and test some of my models. This is cumbersome for a number of reasons: it hogs my laptop, its pretty slow, doesn't use the GPU, don't have enough disk space etc. My question for the community: What sort of hardware setup are you using to do your training?
