Chessbase Laptop

I'm thinking about buying a notebook for Chess and working (no hardware-demanding tasks but I'd like a light and portable notebook).

Has anyone tried a notebook with a Core M 5y10 processor ?

Do you find it powerful enough to handle Chess analysis well ?

Have you got any recommendations for a specific notebook to buy ?

What screensize do you think is optimal for Chessbase ?
(I'm thinking between 13'' - 15.6'')

Thanks !

Then is an i7 Quad (HQ series) much better than an i7 Dual (U series) ?
Is it worth it to go for a Quad (for Chess) ?

Thank you very much for your help.
