Consider your needs and budget to decide between B450 and B550.
Consider your needs and budget to decide between B450 and B550.
I don't believe a 3200G will fit with a B550 as I understand it. For older components, it makes sense to grab a refurbished set from someone upgrading. You don’t have to commit to a system for five years. I usually buy used upgrades every few years when prices are good. Buy low, sell high. Keeping something new forever makes its worth drop. If you're aiming for the next five years, an 8-core option with a used 3700x would be better.
This situation demands a personal decision. We can share some information: the 4000 Series Ryzen is probably the final CPU for the AM4 socket, and these chips won’t work with B350/B450 or X370/X470 boards. So you’re limited to either a B550 or X570 motherboard, or possibly the unannounced X670—if it ever appears. As the AM4 socket gets phased out, you’d need to assemble your own system, knowing that the components you choose will still function for about five years. We can’t foresee what technological changes will come next, and we have no certainty about future consumer tech. By 2021, AMD might switch to a new socket, and DDR5 could become more common in consumer devices. There are whispers it might boost the speed of some DDR4 modules by doubling their frequency, which makes sense given how AMD moved from DDR3/AM3+ to DDR4/AM4. With all this, you have two paths:
1. Purchase Ryzen 3000 or 4000 with its own motherboard chipset (the 3000 line is backward compatible) and carefully select parts to ensure your PC remains functional for the anticipated workloads for five years, accepting limited upgrade options.
2. Hold off until future announcements about AMD or Intel’s upcoming CPU and memory designs. You could wait until around 2021 and switch to a brand-new, future-proof platform, meaning you’d keep using your current setup until then.
