I have a 2.53 GHz uMBP (Late 2008) with 4GB of RAM 1067 MHz DDR3 and I was wondering if there were any other ways to upgrade my MBP? I heard the new June 2009 MBPs can have 8GB RAM and 3.06 GHz. I am a gamer, so I am looking for improving my game's speed- basically the overall smoothness of the game. Also, does anyone have the InvisibleSHIELD for the MBP? Is it a good investment?
