I mainly need the laptop for Office (Excel, Photoshop, Teams) etc. And for playing (GTA, Battlefield etc.)
The problem is I have a little bit of a clue about the components. We a lot of Ram are important, I5 or I7 etc. Core processes etc.
Take a look at https://www.hardwaredealz.com/bester-gaming-laptop-fuer-unter-800-euro-gaming-notebook-bis-800-euro
HP Pavilion 15 Gaming Laptop would give you the most
The link on the page does not lead to any laptop and you get a better device for 800 euro.
