d-c-f is a new member on this form and is unaware about the actual speed that he should get. Had he gone through other threads. specially sticky one, he may not start such kind of threads. d-c-f, don't mind, I will advice you to read the threads or use search.Identical threads divert attention.It is better to continue from the thread already started for that particular topic. And the discussion on 590 NU is still ON on this forum
