i had a gtx 960 sc paired with an A10-7700k but now that ive traded in my 960 for a strix 970 my 7700k is bottlenecking the 970 i was gonna upgrade to 8320 but theres no mini itx for AM3+ at my local MicroCenter they're selling an i3 6100 for 109$ and upgrade to an i5 later on, and will i still get bottlenecked? or should i buy an i5 4590 for 160$? or do you have any suggestions for a cpu to pair with a 970. All advice will be appreciated and my dick is out for harambe.
