New Laptop - Deal or No Deal

[Tums]

Quote from Joab:

Thanks for all your help guys, it's been 3 years since I bought a new rig and I've lost touch with the technology.
One last question:
Is the 45nm 64 bit or not, I'm confused.
Esignal, my data provider says they don't support 64 bit

let's get one thing clear...

64 bit refers to BOTH the operating system AND the hardware (CPU).

eSignal is referring to the operating system.

Win XP is 32bit
Win XP pro is 32bit
Win XP64 is 64bit

Win VISTA Home is 32bit
Win VISTA Ultimate is 64bit


CPU:

Core Duo is 32bit
Core 2 Duo is 64bit

32bit operating system can run on a 64bit CPU
