Hi all, I have a 17" Early 2008 MBP 2.6Ghz currently with 4GB ram installed and have been thinking about upgrading to 6GB. My question is will I notice a performance increase and does it justify spending $114 to upgrade? I'm thinking of buying the 6GB upgrade kit from OWC. I just upgraded to a faster, roomier HD and with Lion out, I was hoping these upgrades would give me a performance boost. If it matters, I primarily use it for Photoshop/Illustrator CS5, Starcraft 2, watching videos and web surfing. Thanks!
