I am sorry I had to resort to posting a new thread on a possibly already answered question. However I have done a lot of research and can't seem to find an answer. I am planning on getting a 15 inch unibody MBP with a 512 MB NVIDIA GeForce 9600M GT. My 3 year old gaming Dell xps laptop has a 512 MB NVIDIA GeForce go 7900 GTX. Is the 9600 better? If so by slightly how much? Thanks.
