I'm checking if the Intel i5-4590 can swap in for the i5-2400 in your Dell OptiPlex 990 SFF. The Dell runs well with the 2400, but I’m unsure about the socket differences between LGA1155 and LGA1150. You mentioned you got the 4590 for free—make sure it matches the correct socket type before installing.
The i5 2400 features a fixed multiplier setting, which prevents actual performance boosts through overclocking.
