What's the reason for getting a generation behind hardware? Is it hand me down or used/cheap? If you are building PC for the first time or still not comfortable yet, I suggest using PC part Picker website. Also, I recommend AM4 Platform. That's Ryzen. I say this because AMD promised their consumers that their motherboards will be compatible with newer CPUs that'll be hitting the market until Ryzen 3. Which is great news for us. All we need is a Bios update from manufacturers and new CPU for upgrade later on if you decide it.
