Biggest (potential) problem with a laptop is for heat ramp-up; if the machine is rested on a solid surface with (good) airflow under the machine, then good.
My personal recommendation would be to look into a pre-owned desktop for a similar budget; research involved may be a bit more intensive, but the gaming experience reward will be commensurate… umm; worth the effort.
EDIT:
If either of the two systems you listed has a reasonable option to take it to 16GB, it’d be worth it - Windows 10 + WoW can easily get you close to 8GB in use.
Thanks for the reply. I figured heat would be a problem, I do play on a solid surface most of the time and usually no more then 1-2 hours so nothing extensive.
Currently the MacBook does get hot but I’m comfortable with that.
Definitely agree about a desktop being a better experience, I just prefer to have that portability when I need it will deffo look at the 16GB thanks for the tip
The key is to check credible reviews like on notebookcheck - they cover thermals and potential throttling capabilities. You find something at a good price and then go to check the review.
1660 Ti based laptops will be quite efficient at 1080p gaming. From previous generation GTX 1050 Ti at the entry level and GTX 1060 as sweet spot at good price could be an option too.
There will be black Friday offers. Lenovo likes to discount stuff. MSI also. You can also check Clevo based laptops (pcspecialist and few other UK shops offter them) which you “configure” as you buy allowing you to select good storage, ram and components instead relying on weird default configs - like the two listed above have 8GB of RAM which is ok-ish, but 16GB would be golden. They don’t list storage (where as you really don’t want a HDD when even 1 TB SATA SSD is super cheap while being much better)
Thanks for the detailed response, very helpful and I will deffo take your advice
I see on the Razer Blade 15 it has GeForce GTX 1070 Max-Q - Are these outdated now? I’ve found someone selling the Razer for a good price, which is tempting me. i7 16GB & SSD
I assume any of these will give me better performance then my MacBook currently does?
1070 max-q is above 1060 and if it won’t be thermally limited then it will be really good at gaming. Check the reviews of that specific razer model (they have few and usually arent cheap). Also i7 can be anything from dual core older U series and up.
