Smile [Q] Does it good if I coming from 10.1 (2014) ?

I ran my 10.1 (2014) P601 for about 2 month ago

I am thinking to swap to Pro 12.2 (P901) ............... (No P605 / P905 in my country)

Price different here is 10000 Thai Baht (about 310 USD)

(mainly use for Hay Day game & Web browsing / Facebook / PhoneCall )

Does +310 USD is reasonable price for my usage ?

Thank you for your suggestion.
