Buying a new MBP Retina, is the top end Haswell i7 worth the extra $200?

Spec'ing out a brand new 15" MBP… I'm upgrading from my 2008 Core 2 Duo model with 6GB RAM. The question is, specifically:

As a graphic designer who uses Adobe Creative Cloud pretty extensively (Indesign, Photoshop, Illustrator, After Effects), will the extra $200 for any extra 300mhz of processor be worth the added cost?

Already the machine is pretty beefy, just wondering what the community thinks.

Hollah.
