I am looking into upgrading my PC this holiday season. My current rig has an i7-4790k, 32 gbs of DDR3 ram, and RTX 2080. The new Ryzen line, specifically the 3700x and the 3800x, have caught my eyes since launch. Now, looking at the options of motherboards, I am trying to decide if the X570 platform is worth the extra money, or if X470 will work for me. Is the extra speed in teh PCIe Gen 4 necessary? I remember a reviewer state that if you didn't know if you need PCIe Gen 4, you probably don't, and I think I fall in this category. To give you an idea of the cost savings that I am looking at: At my local store, I can get an Asus Prime X570-Pro for about $250, where as I can get the Asus Prime X470-Pro for $125.
Is there really that much of a difference?
