Take a look at the requirements.
Thing is that I can get the 8350 for $170 altough if it's really THAT much of a difference I guess I could buy the 3570k.
For Microvolts specifically, the difference is very small.
The 3570K is worth an extra 20-30$. Any more, and, if budget is a big deal, the difference isnt that big.
Either way, 2500K is the eay to go. MicroVolts doesmt use more than 2 cores.
