this reviewer needs to check his brain.
Yes, resizable bar is required for the B580.
Intel specifically states its a requirement.
So, whats there to criticise if you dump it in a system that doesn't have resizable bar.
Intel even uses the word "MUST" have resizable bar. Please think through whether this criticism is fair or not.
Also, please note that the supported CPU generations are stated clearly and the intel 9000 series the reviewer uses is not in the list. He can try it if he wants but it is not in the list and he should be upfront that he is testing it with a chip that is not officially stated it supports.
