Interchangeability of laptop motherboards lenovo G50-30 and others of this series G50-(45,70,80)?

Question

laptops

The purpose of the question, there is a laptop g50-30. With low performance, also with a blocked BIOS (the OS is 8.1 and it is not possible to change, as you understand). Characteristics on later "later" models are more sensitive higher. That's why the question is, does it make sense to pick up a mother from analogues with higher performance or "score"?

Answer 1

True, you can bump into the performance of the cooling system and let’s say that it will not be divorced on the GPU
