I have an acer aspire 7551-7422 laptop. I have upgraded the ram from 4gigs to 8gigs. My question is that I would like to upgrade the processor from a AMD Phenom II X4 N970 to a Phenom II X6 processor if possible. Or a more powerful precessor if an X6 will not work. I will be using it for 3D work, music production and video. I am doing this to try not to buy an I7 laptop if I dont have too. Any suggestions will be greatly appreciated.
