A 9590 is just a hot waste of time attached to an obsolete chipset. Clock speed isn't as important as the CPU architecture and IPC. That 4770 can turbo all core to 3.9GHz consistently and would obliterate an i3 and come close to a 9590 with a fraction of the power and heat dumped.
While it's a little old to be building a fresh system on, that's a bit harsh on the 9590. To be as old as it is and to not have been leader of the pack even when it wasn't old, it's doing quite well. At least mine is. It's bloody fast for the sort of things I do on a computer (apparently).
OP should look into i5's, and try to control your desire to yell at Intel for not being able to name cpu(s)/chipset(s)/socket(s) in any intelligible fashion.
You'll figure it out eventually, keep reading.
