Thanks. I have 656 MH/S.
I am using AMD Ryzen 1950x 16-core. It's still ok to use it for mining VRSC at the moment. As difficulty consistent going up soon it will be obsolete.
I don't know that it will become obsolete anytime soon. Right now, there is work ongoing on a GPU miner, and the last I heard, GPUs are looking like they are likely to be competitive with CPUs, but probably not better when comparing similar cost/power usage.
I have been mining for 6days at 200mh/s and haven't received a single coin.... so I'd say it's probably already obsolete... :/ or people GPU mining and you just dont know yet... not a single coin!
