Is it possible to do it? because most of what I have found online is concerning desktops and DIY. Also, when replacing the gpu, do I have to find something that's compatible with the speed of my cpu, my cpu is intel i7 (2GHz)? or anything can fit in. I'm no expert is this kind of stuff. Therefore, some guidance is needed.
My laptop is Asus N53S. intel i7 (2GHz). 8GB RAM.
