The "refresh" version of the i5 100 Mhz offers more for the same price (this replaces the i5 4570 processor).
Attention! This is an i5 Haswell "refresh" that is only supported by motherboards with a BIOS newer.
In my case installed with a G43 motherboard MSI B85M recognized directly, so no worries.
If the motherboard would not update the BIOS level, you have to go through an i5 or i3 oldest, then update ... which can be somewhat laborious!
Getting back to them- selves performance of this CPU, they are very good.
associated with GTX760 and 8GB of DDR3 Ram, this is a perfect gamer configuration!
For the office, or treatment picture, not worth taking this processor, i3 will be good enough.
Note also that the supplied fan with is efficient and quiet enough to stay in place. (Which was not the case there are a few years with standard fans)
