Trying to decide between the Core2Duo and i5. Will NEVER play games, 3D rendering etc. Will: Upgrade RAM to 8GB Surf internet Watch movies either itunes downloads or DVD Edit photos in Photoshop elements Possibly edit movie clips from my digital still camera Yes the i5 is faster on paper and has the 512 video card but can I see or feel the diff in all of the above (based on an immediate RAM upgrade that I will do for both the base 27 inch c2duo and i5)? I don't want to just have an i5 for the sake of having it if it's never used, you know what I mean. Not concerned too much about future proofing since I tend to be a tech buff that flips my equipment every 2-3 yrs to have the latest toy and even the i5 will look old by the time the next iMac redesign comes in Fall 2011 with maybe Quad Core 3.8Ghz or USB 3.0 or OLED screens or who knows what. Advice most appreciated. Thanks everyone.
