Cat5E is all you need for 10/100/1000.  Cat6 is said to support 10G over
copper when it is common place.  If I was going to wire a corporate
building I would go with Cat6 in the walls.  Cat6 patch cables only if a
problem showed up.  But I've never had a problem with GigE speeds and
good Cat5E.  Cat6 is the next generation cable and is designed to handle
a higher spec than Cat5e.  There shouldn't be any case where a healthy
Cat6 cable performs worse than a healthy Cat5e cable.

To a vendor the difference between CAT5E and CAT6 is about 2 cents a
foot.  They charge quite a bit more than that at your local compusa
