I plan to build a system with six AMD R9 280s. My first question is, would it run smoother with at least one CPU core per GPU? I am planning to get an 8 core CPU. Is that overkill?
How much system RAM would be required? I was thinking 2 GB per GPU for a total of 12 GB. Is that enough?
One last question, how big of an SSD would be ideal for this system? I plan for it to be a dedicated Ether mining rig running 64-bit Ubuntu. Will I need a large amount of hard drive storage as the blockchain grows?
