difference between October 2011 and June 2012 pros

other then USB 3.0 are there any difference between the two? I only comparing the ports and not the video card or hd.

Newer generation Intel processors, A bit faster RAM, new graphics cards, and USB 3. That's pretty much it.

No real port difference other than USB 3.0, but it does run a bit quieter and cooler. Also, beyond CPU & GPU differences, which are quite significant, it can take 1600mhz RAM and Bluetooth is updated to 4.0.
