Hi, I am new to Mac Rumors, thought you might help me figure out how to make my 2008 iMac 3.06 GHz Intel Core Duo be faster. It has a NVIDIA GeForce 8800GS graphic card. I just upgraded it from Leopard to Snow Leopard, and I am downloading the software updates to get to 10.6.7 I currently have 2 GB memory (2 x 1GB DDR@ SDRAM 800MHz). Can I install more? How much more? Do I need to bring the computer to the Apple Store or can I do it myself? Also, I only "upgraded" from Leopard to Snow Leopard. Would it be better to do a "clean install" as I read on some forums? I might upgrade to Lion or Mountain Lion so that I can use the iCloud. Is there any other advantages in upgrading? What else can I do to have my computer be faster. I will be installing Adobe Creative Suite 6 and want to make sure it won't be too slow. Thanks!
