Alright here's my predicament. Since no new iMac came out after doing some thinking I came to the conclusion it would be nice to have my first mac be portable so I could go with the MB pro and then get a refurb. thunderbolt 27" display. With the educational discounts and tax it comes out to around $2150. Not too bad. That's for the i5 though. I'm a photographer so i'll be mostly in photoshop and lightroom. Besides that just your regular web browsing and things of that nature. Now would that i5 serve me well and be nice and fast? Or is the i7 really worth the extra few hundred dollars because it makes such a difference? I'm trying to keep costs as low as possible while still getting a good setup for what I want. Will I notice a difference between the two working in CS5? I'm currently on a year old toshiba laptop with a 2.3ghz i5 and a ****** graphics card. I really like the apple display and the OS better than windows and think it's time for an upgrade. Thank you all for the help.
