Hi. I have an asus x54h laptop with x54ly motherboard and intel celeron b800 1.5ghz dual core and I was thinking of upgrade my current motherboard to k53sv motherboard. What I would like to know is: is it worth upgrading it and how do I know it is compatible with my model x54h? What should I pay attention to if I want to upgrade a motherboard in a laptop? Thanks in advance!
