As far as i can tell you, Galaxy Computers, https://galaxy.pk/ is a good place to buy laptop in Pakistan as they provide you Online order and shipping facility and they also have a outlet in Lahore. Other than that, maybe some members from Lahore can help you out.
Btw if you are purchasing a high-end laptop you can also import it from US or can purchase from PG Premium sellers. Do visit PG Market-place section and specially Premium Sellers hub
@mtariqsajid I doubt you will be able to find 10 gen gaming laptops with the current market situation. I suggest you check out out PG market place, some of our members are selling high end machines in reasonable prices.
Additionally you can browse shops in Hafeez Centre some on the second floor deal in open box gaming laptops like Asif Computers and Acom computers but beware some laptops are refurbished do check a laptop thoroughly before buying.
Not in Lahore but you can check and buy online from CZone Karachi
They added new laptops in stock just last week
I have bought CPU coolers, motherboards, network devices from them multiple times and their delivery is the best
