Hot damn. I noticed I said 3700X when I was talking about my upgrade, then I realized that was wrong because I bought a 3600X which was $100 cheaper.
But then I remembered I replaced the Ryzen 5 sticker on my case with a Ryzen 7 sticker...
Check CPU-Z and it's identifying the chip as a 3700X. Go dig up the box, yep, the serial sticker says 3700X. Receipt says 3600X even though it includes the serial for a 3700X on it. Just got a $100 upgrade for free. Someone either screwed up when bundling my order or did me a huge favor.
