What could my Core 2 Duo not do that the more modern processors can?

For example if you compare the i5 and i7 processors of rMBP with the 2009 Core 2 Duo, what would be the difference in concrete terms?

Less efficient. More power used

What about speed? What kind of activities would lack of speed show?
Just browsing with a browser I guess wouldn't make much of a difference?

There's no difference. The difference is in an SSD vs HDD for IO speeds, battery life, and weight (thinness). I use a 2009 MacBook with a Core 2 Duo CPU, and it's more than good enough for youtube/facebook/word/etc...

Would a difference only show in saving a long video?

No. Saving a video is related to IO, and if you have an HDD or an SSD, and even where you're saving the video from.

You can easily upgrade the older mac to an SSD, and you wont have any difference is saving videos at all. Now if you're using iMovie or Final Cut Pro to edit videos, you'll notice a big difference in speed between an old and new mac... but otherwise no. If the video is from online, no, there's probably no difference at all as that's internet speed related.

That's what I meant. iMovie or Final Cut.

Can you use the SSD to save and use HHD as the place where the videos are saving to?

You're thinking of caching while it's compressing something. That isn't worthwhile. I'm not even sure if what you're thinking of is supported by those apps.
