id buy the cassette now and have it waiting in the wings, youll need it eventually anyway. youll know whether the old one is usable or not after a good test ride with the new chain.
if you’re good about replacing your chain before it gets excessively stretched, cassettes can last quite a while. But you can wear one out with one chain if you’re negligent.

General rule I’ve learnt in a bike shop. If the chain has worn by 0.75 then you’ve probably been running it with a worn chain. If it’s only 0.5 then you’ll probably be good for a few chains. Myself on my bikes I try for 3 or 4. My cassettes are expensive lol.
It’s difficult to tell in the photo, but some of the teeth in the middle sockets seem to be worn

No way to tell from a picture. Put a new chain on. If it skips you need a new cassette.Â

I’d replace the chain and cassette and then you don’t have to worry about either. You’ve clearly gotten your moneys worth out of it. Trying to squeeze more miles out of it with so many damaged teeth on the middle sprockets could end up damaging your new chain and I wouldn’t want anything to happen on a ride.

Replace the chain at 0.5% wear (measure with a proper chain wear tool like Park Tool CC4) and a cassette will last for ~4 chains.
If a new chain skips or makes a lot of noise it’s time for a new cassette.

It’s the cs-m8000 probably has about 2500 miles on itÂ
its impossible to say for sure from a photo, here’s the tool for measuring.
