here we go again:

Quad core processor:
Q6600 or newer

4GB of 800 MHz or 1066 MHz Ram

Nvidia 8800GT or 9600GT or better

2 Hard drives, one for OS another for WoW installs.

At least a 500 Watt Power supply

I also suggest vista 64 to take advantage of all 4 GB of RAM, although a number of folks will disagree.
