I'm looking to move to all AMD. I was going to get a 570 board with 3600 RAM and then drop in a 1600 until I have the cash to get an 8 core 3700x or even a 4000 series cpu. Is this wishful thinkin gor a sensible option? I'm thinking to get a good 570 board now for later on as some of the 470x boards don't have 3600 ram support speeds
