I am am upgrading some of my network (its an ongoing process), and have upgraded my router's & switches to gigabit speeds already and most of my pc's already have gigabit nic's. There was a noticeable improvement with those changes.
Is it worth it to upgrade from the cat5e cables I have? Will there be a noticeable difference in performance? I have been reading reviews and specs. and still can't decide if its worth it, if you have used and noticed a difference, let me know. The cable prices (in the pre made cables, I wont be making my own with these) are pretty close between the different versions, so that is not a concern either.
