I'm about to buy a laptop mainly for traveling (my main machine is a Mac Pro 5.1) and have these two to chose between: Brand new 13" Macbook Pro (mid-2012) 2.5 GHz i5/HD-4000 Second hand 13" Macbook Pro (late-2011) 2.8 GHz i7/HD-3000 Both machines can be upgraded to 16GB RAM and the hard drive replaced with an SSD, but the i5 has a faster graphic processor (HD4000), Thunderbolt and USB-3. The i7 on the other hand has a faster clocked and more powerful processor, but is that enough to make it a (noticeable) faster computer? It'll be used for Photoshop/Lightroom editing and photo organizing in addition to basic tasks such as email/web etc. It's possible I might be using it to make music with as well (DAW software such as Logic, Cubase etc.). I'm leaning towards the i5 because it's brand new in the box, has newer technology (USB-3, Thunderbolt) and has a more powerful graphic processor (HD4000) which I assume might be good for Photoshop and Lightroom use. Will this make up for the i7's more powerful/faster processor?
