suggest laptops in exchange for prayers :)

im a cs undergrad looking for a 16 gb ram 512 gb ssd i7 10th gen or higher laptop with a decent gpu for later courses. the ram and ssd should be upgradeable for future. need the laptop for coding, readings and maybe editing. budget is 1-1.5lacs but could go up to 2lac. need it to last me at least 4 years for the entirety of my degree. so if u have suggestions for better/more suitable specs, let me know that as well. also, should i purchase it from pakistan or saudia arabia? where might i get a better deal for an authentic product>
