Normally I'd say that's dumb and just wait, but Micro Center has a deal with free RAM with a purchase of a Ryzen 7000 CPU right now. The cost of the RAM by itself is higher than I would lose reselling a used 7700X. And I doubt the deal will apply to the X3D CPUs when they're a brand new release.
I also just kinda want to put together a new PC lol.
