Witch CPU is the best?

[macpascal]

I'm looking to buy a laptop and the ones that mostly fit my needs for now are equipped with either one of those processors:

-AMD Dual-Core Athlon 64 X2 Mobile

-AMD Dual Core Turion 64 X2 Mobile

-Intel® Core™ 2 Duo


Witch one is usually rated as the fastest?

Witch one should i choose if i'm planning to watch hi-res videos, basic video edition and conversion, use autocad/solidworks ans surf the web?

How to know what processor is used when it's mentionned Intel Centrino?


Thank you in advance!
