Optimal CPU and motherboard pairing for 1080p at 144Hz
The motherboard works well with both 9900k and 9700k models, though the 9900k option isn't the best value. The cooler performs adequately for 9900k but should comfortably manage a standard 9700k build.
The listing for the 9900k on Amazon is for the US market, though the i7 9700k offers a more attractive price. It looks like a solid upgrade from the 8400 and should last through most of your PC's life. Probably the next step will be a completely new machine.
