I have an unopened 14900k, which I received as a replacement after RMAing my original one due to a degradation issue. I never got around to reinstalling it, so I'm just looking to sell it, asking $350 for it.
I also have an ASUS ROG STRIX Z790-E WIFI II motherboard available for $250.

Feel free to reply, and I'll get back to you as soon as I can.
