Alright all, My current rig is creaking a bit as it hits it's fifth year this year. I upgraded to a RX 590 a year ago but now I'm looking at mobo/ram/cpu upgrade in order to pass down some bits to my son. Just a few questions: B450 or X570? I don't want to have compatibility issues as I don't have 2000 series CPU lying about. Looking at Asus ROG Strix B450-I currently but I really don't want to receive a board I can't use. Anyone had hands-on experience with one or similar system in last few months? It needs to be mITX to fit in my current Corsair 250D. Does this make a difference to the chipset question. Likely going for 3600Mhz RAM because why not. I've heard that here is where the differences will become apparent between the chipsets? If I went X570 is it worth splashing more for a 3700X? Conversely I'll need a mITX case for my son to house these - what's the current decent-ish price version of my 250D or anything in this class? Thanks for reading and appreciate any replies.
