We use gig ports for our core switches. I use both CAT 5e and fiber for have noticed no difference, but utilization was about 8 to 10 percent.
If the distance is within a few feet or the same rack, I use CAT 5e. If I have a run from one end of the building to the other, I use fiber.

Is there any real difference, if I use a copper RJ-45 port, or a fiber port, if both are set to 1000T?
