    I appreciate the competitive pricing on this CPU. It competes with new processors at Ebay prices instead of normal retail. You can always get a deal on old hardware on Ebay. Now Newegg is competing with those people! It ensures for another $20 that you are getting American hardware and not Asian CPU's from overseas that may be unopened as well, like Igot Not to mention the legions of listings for "CONFIDENTIAL" processors of all kinds from China. Talk about something you don't want to buy.

    12900K - an excellent buy

    Had a 11900K prior to this one, and as fast as it was even being overclocked to 5.3 ghz - the 12900K is just simply better. Put a minor overclock to 5.2 ghz and it's been so nice. P cores are freed up to do what they're supposed to do. E cores do the chores! Was hot at first before undervolting, but now that's done and temps are high 70s with a 360 mm Corsair AIO. Paired up with a Z690 from MSI and a RTX 3090 it's just the perfect combo. 12900K is completely free to do the data processing for the game, and 3090 handles the graphics side in all my triple A titles without needing to borrow from the system memory at all - needing to pull data through the processor. Resizable bar enabled and it's been awesome. Was worth every penny.

    It's been up and running for several weeks now and is performing better than expected. I've had absolutely no problems with installing and testing. Great communication from seller and would definitely buy again from them.

    Great upgrade from old 4770K

    This is a great upgrade from my old 4770K, much faster. Make sure you get a good CPU cooler, I'm using a Corsair iCue H170i Elite Capellix to keep the CPU cool.
