Well thanks to both of you for replies, but I decided that I'm getting i5 2500 it's has the same pros as 2400 but it's better
, thanks again.
Spring for the i5 2500K. Note, you can't change the multiplier on i5 2500 without the K suffix. So you'll be stuck at stock speeds (with a tiny variation of the BLCK).
I run the i5 2500K at 4.5ghz 24/7 at vid volts (max temps 65C at load). Highly recommend.
