The problem with gaming laptops is that they overheat; a LOT.
When it comes to desktops, 75c GPU temperature is considered EXTREME. On the contrary; laptop GPUs often exceed 90c in hot climates; which means they tend to have a very VERY short lifespan, most go belly up after 3-5 years.
Plus there's the small screen, hefty weight (Comparable to USFF desktops), loud cooler noise, expensive parts and even slight dust accumulation will spell doom on the hardware, as it operates near boiling point temperatures as it is.
I wouldn't recommend gaming laptops in Pakistan, or even USFF desktops.
