I've been looking at gaming laptops and my budget is between £1,000 to £1,500. I don't mind sacrificing the weight for High performance and Less noise and heat. Aside from gaming I'll be using it for game development (Unreal Engine, Autodesk and Gamemaker). So far the ones I found are ASUS G751JT, Alienware 17 and MSI GT72. Any suggestions or advice?
