I'm thinking of buying a laptop that I can at least play games from time to time.
Run games like z. World of Warcraft Retail or Classic, Heroes of the Storm, League of Legends, Starcraft 2 or similar. On low graphics settings on the following system:
Intel i3-7020U, 8GB RAM, Intel Hd 620
The graphics card is definitely not enough.
It's best to spend your budget, then people may be able to give you recommendations.
Well so 400 euro.
