Hello, I've been searching for hours and hours and couldn't find a satisfying result to my question, since virtually everyone seems to have a different opinion on that topic... yet none seems to have compared the CPUs by themselves. I'm planning on getting a MBA 2013, 8GB Ram, 128GB SSD which will cost me $1,199.00 w/ the i5 and $1,349.00 w/ the i7. That's a $150 I could spend on an external hard-drive (since 128Gigs isn't exactly huge, though sufficient w/ iTunes Match). I'm not sure how the real-life advantage of the i7 is in the following topics: Video editing / Rendering (not terribly often, but I do that from time to time) RAW-editing photos from my DSLR Since the HD5000 seems capable of it: Some gaming from time to time Programming & Real-Time-Debugging w/ Eclipse Benchmark show an increase in speed up to 25%. How noticeable will that be in everyday's business? If a movie were to render 15 instead of 10 minutes, I wouldn't really care, but if my editing software would start lagging and crashing, I most certainly would. I wanna use the MBA for at least 2 years and don't have an iMac or any other big machine, so the MBA is gonna by my desktop-replacement. Thanks in advance!
