Quick question: I have a 2010 MacBook Pro, 2.53 GHz Intel i5 with the 256MB NVIDA card and I'm selling it to a friend. I need something with a larger screen for image editing. The resolution on the 27" iMac is mind blowing, so that's probably going to be my replacement. My question is: Will I be fine with the i3, or should I really invest in the i5 processor? Also I'll probably be upgrading the graphics to the 1GB instead of the 512MB card, isn't confirmed yet. The most intensive programs I'll be running is probably photoshop and aperture. So I know I SHOULD upgrade just to be safe, but I'm also a poor college student...so...pinching pennies everywhere I can. Thanks.
