Great Upgrade from 9900K

Great Upgrade from 9900K
So far this thing is great! I upgraded from the 9900K and this has been a noticeable difference. I'm still in the process of updating drivers and reinstalling some software. I haven't done any overclocking so the Cinebench score and temps are straight stock settings.After seeing all the info on how hot this thing can get I added the Thermalright contact frame. It was a breeze to install. I watched the Gamer's Nexus video about this frame and followed their directions.For the motherboard I went with a MSI Z690 MPG Edge Wifi DDR4 so I could reuse my current RAM. I had to order a LGA 1700 bracket for the NZXT Kraken X73 AIO. I ordered both the frame and the LGA 1700 mount from Amazon and both arrived fast and were exactly what I needed.So far my temps are staying in the general range of my 9900K. I'm planning to do a little gaming this week with it so I'll have a chance to see how it does under my daily use. I also do a bit of Premiere and After Effects so I'm looking forward to seeing how it works there as well.Overall, this is probably way more processor than I NEED. I was still able to do what I needed to do with the 9900K. I built the 9900K in 2020 during the height of the astronomically high PC price wave. I ended up getting this processor for about $100 less than I paid for the 9900K two years ago. So the price-to-performance upgrade for me was a no brainer.If you want a fast processor at a reasonably decent price, this is a great one to get. Just be aware you will need to pay attention to your cooling.
