New MacBookPro 15 - i5 or i7?

[yeric]

The only difference I see between the new MacBooks tomorrow is 1MB of cache and 100MHz of clock. Am I overlooking something?

If those are the only differences, it would seem to me that the i7 option would only be worth $50 upgrade (to me).

I have an 8GB i7 with 7200RPM drive at work and it screams. I don't notice any slowdowns when running Fusion. But I'm sure an i5 would be plenty for most uses.
