I hope you put CAT5e in and not CAT5
I would not bother with CAT6, as its far more difficult to put in, you have to take in to account the bend radius, which is far less than CAT5e. There is very little performance difference over 1Gb (50m runs)..... CAT6 is only worth it if your going to put a 10Gb switches in and 10Gb network cards in all your equipment.
