Good answer. Thanks. I'm running Simplify on two different boxes. An older dual core Phenom (3.3ghtz) with an AMD R5 350 video card and a new Ryzen 1700 with an R( 390. The new box is blisteringly faster. (i'll do some numbers and get back) I am going to upgrade the old box and wanted to put my money on the right part.
