Same cassette. I figure when I've got 6500 miles I'll change it.
I'd be disappointed if I didn't get twice that mileage from the chains and cassette. How are you measuring the wear? Chain checkers are not accurate. There is no point in replacing a cassette if a new chain does not cause skipping with one or more cogs.
