Need advice on AMD Turion 64 X2 TL-60 processor

I am trying to figure out which processor to choose.

The price difference between two laptops is $500, and the biggest thing I am concerned with is the processor. I understand the rest of it.

The cheaper option has AMD Turion? 64 X2 Mobile Technology TL-60 (2.0GHz/1MB) processor.

It is my understanding that an L2 cache of 1 MB is not the greatest.

I am not playing online games, mainly running Office 2007, QuickBooks, Tax software, etc.

The more expensive laptop has an Intel? Core? 2 Duo T7250 (2.0GHz/800Mhz FSB/2MB cache)

How much difference would I really notice?
