I upgraded from an 9900k to the 12900k, and it a beast more than double the performance of the 9900k given me more pcie lanes and not to mention no need to upgrade to new cooling solution as my old 360 aio can be fitted with a cheap 3 pound retro fit kit from corsair. Overall super happy with the produce and ccl computers. The price was cheaper compared to other retailers and AMD equivilant cpu, the delivery time was short got it within 2 days of ordering.
