Need advice! My rig is equipped with 2 Radeon 7990 and one r9 280, total 1450 sols/s. Very pleased! My aim is to mine enough coins to buy newer gpus that Are more power efficent without losing speed. Any suggestions? My mobo can handle 3 gpus max.
rx 480s currently that are priced closed to rx 470s. If the price of 470s drops then pick them up but if you can get a 480 for 470 price it makes sense to get 480.
5xx not worth it.
