I just got the Dell Inspiron 7000 15 inch Gaming laptop,
(i7 7700HQ,16gb Ram, 1050Ti etc.) It'd be perfect.... apart from the fact it's 2.65kg or so
If price doesn't matter, then i'd go for the Razer Blade, because If your country supports it, you can get 5% off through their education program if you sign up using your student email or whatever.
and its also, super powerful for the size
