So I upgraded my motherboard to the Asus ROG Strix B450-F with a Ryzen 5 and I had 2 gtx 1070s in SLI but this motherboard does not support it only cross fire so was thinking if I sold the 1070s and got a AMD equivalent not sure what that would be? i heard the RX Vega 56 is the best option but was trying to find something around $200 for each gpu or if i should just keep the 1070s but would be a waste right? only thing I heard you can do is use them separately for different tasks. I mostly game and some light video editing.
