Hi guys, I wonder which upgrades options really worth with the new rMBP. So there are 3 upgrades for CPU + 2.4Ghz i5 + 2.6Ghz i5 (add $90 more) + 2.8Ghz i7 (add $270 more) I definitely go with the 16gb Ram so I just want to ask if it's worth the extra money in upgrading CPU? If so, which one should I get.. I mainly use it for basic schoolworks, streaming video to TV, league of legends and alot of HD movies. Thanks in advanced!!!
