Finally i am getting some CPU WU's!
At long last my new 3900x gets to really stretch it's legs doing something useful
The difference between CPU and GPU performance is insane here, the CPU WU takes roughly 24 minutes to complete, the GPU WU is estimated to complete in 3+ hours....
Perhaps the amount of work to be done differs, i don't know, but it looks like i made a wise decision upgrading from a 2700x to a 3900x...
