Thank you very much for the suggestions @ Jasonwynngard.

Yes , I intend very much for those Ram additions and SSDs .
 I completely agree with you vouching for the durability and hardiness of 'Gaming Laptops' and also knowing what Gaming Laptop brands to choose and look for, I have a Lenovo Y500 ( i7 3000 series GTX 650M) mid range gaming laptop still working after 8 years of rigorous outdoor shoots and studio work (No gaming).
I also use the Nvidia Studio Drivers option and not the Gaming Drivers. 
An HP Omen Gaming Laptop with RTX 2070 super is equal or even more in performance and to a Professional  doubly priced  HP Z 'Work Station' Laptop using a  Quadro RTX 4000 or RTX 3000 .
Thanks
George
