Quoted from SilverWings:Theres a ton of info on processors that will work with this MB. I went with the upper end in terms of performance in terms of passmark scores: the i5-4590. Refer to post #9212 this thread for more info on passmark scores:

The interesting question is if this game makes actually use of the additional cores/threads an i5 would give you over an i3 or if the higher clocked i3 is actually better despite being overall weaker and cheaper.
