I'd say wait if you aren't in a hurry, then you can chose between the dead end LGA1700 platform, or the brand new AM5 platform with a potential 3-5 year life span for CPU upgrades. I certainly wouldn't be buying the overpriced 12700K's etc. right now, even the 12400 is approaching £200, while the R5 5600 is now down at £130, madness!
Yep I am now 100% bought in to to this. Like I said, I can get my kicks from ordering my WC parts and practicing bending hard pipes in the mean time
