Should I Upgrade to AM4 or AM5 for My PC Build?

Just as a note, power efficiency isn’t the only factor in longevity. A solid motherboard, good PSU, and quality cooling can handle high power usage effectively. But honestly, your A320M is pretty low-tier, and pairing a 5700X3D with your current GPU might be overkill for most games, especially if you're on a budget. AM5 is expensive, and you might end up spending $2,000 on the whole setup when aiming for a good gaming experience. Just for context, a decent entry-level AM5 build can cost around $400 just for the CPU and motherboard alone. If budget is tight, you might get better overall value with a strong GPU rather than going for the latest tech.

All that said, if you’re mainly looking for performance, upgrading the GPU should be your priority. The 5700X3D is great, but in today's market, a solid GPU could be your best bet for improving gaming performance.

I'd personally lean towards AM5 for future-proofing your setup. It opens up more options for upgrades down the line, so you won't feel stuck in a few years.

Since your motherboard is on the cheaper side, jumping to AM5 might be a good call. It sets you up for better performance right out of the gate.

Upgrading from a 3300X to a 5700X3D would be a huge boost! It can handle pretty much any graphics card, so if you can swing it, a 9070XT would complement that well. Also, consider bumping your RAM up to 32GB to improve performance in games. Just don't forget to update your BIOS before switching in the new CPU!
