Sell laptop, how much is still worth it?

I want to sell my laptop and would like to ask you how much more you can ask for.

I have an hp by omen 17, original price: 1300 euro about 15 months old.

Data:

geforce gtx 1050 ti

intel core i7-8750H cpu 2.80GHz

8GB ram

1 tb memory + 118gb ssd

How much can I still sell him estimated? It still works completely; has no restrictions or something so great condition

I would start at 600

400-500

So about 600 - 700.

Would start at around 750 euro and go down to a maximum of 600 euro.

So 800 euro. You could sell him well for the money.
