Yes and yes. The newer i7/i5/i3s are fastest (codename Sandy Bridge). You'll know they are the new ones as they have 4 digits after the processor starting with a 2 (e.g. i7-2600).is I7 best for photo editing or should i consider I5 or I3
they said a 15"macbook pro would be better for photo editing
There speaks someone who doesn't process large amounts of data. My half decent E8400 looks like something out of the ark compared to the i7-2600K machine I have now (it's a good 2.5-3x quicker in the standard PS benchmark). That translates to quite a noticeable difference when you're chundering through 22Mpix RAW files in PS or LR....Is gaming going to be the main use for it? if not you really don't need an I7 (or an Ianything) processor, a half decent processor and 3-4Gb of memory will do very well.
