Not if they're fully wired. 

10 and 100 Mb/s ethernet on twisted pair uses 2 pair. Gigabit 
uses all four pair. I haven't seen any vendors selling cheapo 
2-pair cable and pretending that it's the real thing, but that 
doesn't mean that someone hasn't done it. 

For a short haul, gigabit will do just fine on Cat 5. 
Technically, it should work out to the same 100m as Cat 5e...
