Is my system sufficient / notebook?

Don't know my way around very well, but can i play current games well and fluently?

Possibly not on max settings, but yes

Yes, no, technically, if the cooling solution for this laptop is sufficiently dimensioned

I have external cooling on the notebook, so the air gets endlessly, the notebook is from MSI I heard they have a good cooling system.

Yes, there's an effort, but everything is also a question of cost.

A very cheap laptop with good components inevitably has to compromise elsewhere.
