I doubt CPU performance!

Hey, guys.
I have Google, I've looked at Intel's specs page, I've looked through the search function, but I could not find the answers I seek.

I need a laptop and the choice is Intel Core 2 Duo T8100 2.1 GHz 800mhz FSB, 3MB cache and Intel Core 2 Duo P7350 2.0GHz, 1066MHz FSB, 3MB cache.

I can not find anyone's test or chart giving insight into their performance. What CPU is preferable?

Several said that the T8100 is a little louder, as some aquamark3 charts also show but I do not know if it gives a true picture?

T8100'ern sits in a 3Gb 667MHz, 320bbg hd, GF8600M-GT 512MB
P7350'ern sits in a 3Gb 667MHz, 250GB hd, GF9600M-GT 512MB GDDR3

Will you be using this new one for gaming?

It is not inconceivable now and then, but it is not the way some of the new games, etc., probably a little Max Payne 2, Counter Strike or similar.

Okay

I do not how much hard disk is, so I think I will suggest P7350, is good enough not just seen some test though.
