[Wine] What is 'CPU' memory?

Everyone, I'm sorry for the screw ups. Gmail and I had a major argument and
my fixing didn't work. I hope this one does. A moderator is welcome to
delete my mistakes. Or leave them alone for comic relief.

My first thought was the different kinds of CPU cache memory, but their
totals are much less than 2GB. An article on Wikipedia makes a clear
distinction between cache and system RAM.
I believe the following to be valid:
Wine is a 32 bit program
WoW is a 32 bit program
Very broadly speaking, 32 bit only deals with a max of aprox. 3.2 GB of
I have seen discussions (here and/or WoW) that suggests limiting what
Wine "sees" to 3 GB of system RAM
Anything over 3GB is wasted and may introduce a fubar factor
Whatever your hardware can do may not be what particular software
The Windoze comp may be sharing system RAM with the video card (check
BIOS for that)
WoW has raised the graphics bar again, Shader 4 support is now required
to use some settings at max
MS Direct stuff uses hardware differently than OpenGL
That's the closest I could get to "CPU memory".
