I'm wanting to put a rig or 2 together. not sure if i should go with the gpu and or cpu route. (ryzen/server/or standard btc boards) and if I should (wait for vega, get 470s' or 480's)  I mostly want what is profitable and cheap
Not too sure about which hardwaare to get, because I potentially want these to be able to be used as gaming rigs sometimes. but these being able to be gaming rigs on the occasion isn't necessary at all but would be a plus
any ideas would be great.
I also have an option on electricity to have free electricity for 11 hours of the day and then its about 12c kwh. I'd probably would just mine during the night time if I did that but not sure if thats the best option, my other option is 7c kwh and id mine 24 hours instead
Any ideas or opinions are welcome. thanks
