Hello all. This is my first post here. I just started getting into mining.
I currently have a handfull of computers CPU mining and its working out ok. I see lots of posts about GPU mining rigs with 6 cards etc.. but I would rather get 1-2 cards for each desktop I have lying around and just run individual machines with GPUs instead of a racked rig. Power isn't a concern and my space is an air conditioned 20 x 20 server room.
What GPUs should i be looking for used/new that I can find in the $100-200 range for a good hash rate?
