Hi teh link you provided is for teh Intel graphics drivers... which is why you cant update them as i should imagine you will be using NVIDIA GeForce GTS 250. So there is no need for any specific drivers for your CPU. You could indeed update teh chipset and nvidia GPU drivers
Hi, i understand that this is an old post, but, your answer didnt really help anyone looking for i5 drivers, you just said this specific person didnt need graphic drivers for the i5 processor, which is understandable, and "correct" but, when i google "I5 650 drivers" this comes up, and the true question is not answered. no one told him where to get them.
