i7 12700K is Really good and leaves plenty of headroom for future-proofing. Paired with a 30 series GPU it still has plenty of room for a beefier Future GPU. The 2 Extra cores on the -H are barely noticeable when compared to a Desktop CPU

Right, but the performance of the 12700H is very good considering how much more efficient it is compared to the K (Desktop) version.
