Now this is all my opinion from my experience. I play rs on my laptop with a purchased mouse (cant stand the keypad mouse) and i honestly think it runs alot smoother then any pc ive ever played rs on. Ive whitnesed alot of rs on many laptops, now if you wana go buy a laptop specifically built for gaming im sure thats better, but overpriced and not capable of doing much else except gaming. But with name brand laptops i would highly recamend the HP's, specifically with the i5 processor which is just a little more but well worth it. lightning fast internet with very slight to no lag in rs, in fact even less then any pc ive ever used for this game. But again this is just from my experience and my thoughts
