[D] Simple Questions Thread August 30, 2020

Sorry for yet another "which GPU to buy" -post, but I have a hard time deciding and would like to hear your opinion. I am building a PC that will be used for deep learning. In this price range the choice narrows down to either a second hand GTX 1080 Ti or a new RTX 2070 Super which I can buy for the same price (RTX 2070S is slightly cheaper). I am fairly new to deep learning and want to explore a range of different kinds of models. Therefore my focus is on a well-rounded GPU rather than optimizing for a specific type of networks.
