Windows Vista System Requirements

After looking at my friend's quad core 4 GB RAM Nvidia 8800 GT desktop equipped with Windows Vista Ultimate, I decided to take a look at the minimum Windows Vista system requirements.

Here is what I found on Microsoft.Com on Windows Vista Home Premium+:
-At least 1 Ghz processor for 32 bit Vista.
-At least 1 GB RAM.
-40 GB hard drive space, minimum, with 15 GB space available.
-128 graphics card capable of DX9.

ZNET believes that is inaccurate. These are the requirements it state that is needed to run Vista "properly":
-2.0 Ghz dual core processor
-2GB RAM.
-256 video RAM graphics card, need to be able to support DirectX 9.
-100GB Hard drive, 50 GB free.
