I went from i9 11900KF to i9 12900KS last month about 6 weeks ago not having been able to get i 13900KF which was my original upgrade path. And then I just was ablet o get my hands on the i9 13900KF. I am letting this i9 12900KS go reluctantly taking some loss. I ve used it barely 1 month and it is in perfect condition along with its collectable box I would have loved to keep the box but I thought maybe the new owner would appreciate having the box. Beware that this one requires LGA 1700 so those with LGA 1200 or older that would be Z590 or older will not be able to upgrade to this one without having to acquire a new motherboard Z690 or Z790. Please ask any questions before buying. Thanks.
