Your advice is all solid, and it sounds like I'm in the same boat as you
(last four PC's all self-built, self-upgraded, including Linux servers,
a dual-cpu mobo, etc) but I'm trying to depart from theory and dig into
the real memory usage of WoW a bit... After a long (6 hrs) WoW session
today, for example, I have the following stats from Task Manager:

physical memory: 1,000,000 kB
commit limit: 1,200,000 kB
commit peak: 761,000 kB

The pagefile is a nominal size of 256 MB to keep a flaky OS happy. The
1,200,000 kB limit reflects the physical + pagefile - some kernel stuff,
so it's all consistent. As you can see, WoW and the various background
processes never exceeded 761 MB in six hours of play, many zones and
capital cities full of textures, lots of AH activity, etc. In other
gaming sessions I've never seen the peak exceed 800 MB, so these results
are typical.

What I'm wondering is, has anyone seen their WoW (*not* including a
bunch of browsers, MS Office, SETI, etc, eating up RAM as well) ever use
more than 1 GB? Clearly it seems like it could use the extra space,
given the constant disk activity I see, but does it actually *do* so?
