Is the i7 2.3 Ghz CPU significantly faster than the 2.2 one?

Question

I'm shopping for a 17-inch MacBook Pro and trying to figure out my minimum specs.

From the Apple website it appears these are the two procesor options...

2.2GHz quad-core Intel Core i7 processor with 6MB shared L3 cache; or optional 2.3GHz quad-core Intel Core i7 processor with 8MB shared L3 cache

Do the additional .1 Ghz and 2 MB of cache make the 2.3 Ghz model noticeably faster?

(I do understand that HD access is usually the biggest bottleneck, but for my particular tasks CPU speed does make a difference.)
