Just recently I bought updated Macbook with Santa Rosa processor and new Intel video chip. I have 2 sticks of memory with 512 mb on each and using Leopard I feel it is not enough. As I like playing computer games I would like to find any ways to do it. I know it is not possible to replace graphics card with newer one, so, how can I increase the power of GMA X3100? It has 144 of virtual shared memory, is it somehow connected with virtual memory? For instance, I upgrade my memory and get more productivity of graphics card, do I?
