My main machine, running only one copy of WoW -

Core2Duo 3ghz
Geforce 8800gt 256mb
2GB system ram
Faster SATA HDD.

When I'm in Dalaran, my WoW.exe hits 1gb + system memory used. Due to all the players there, it jumps way up.

ANYWHERE else in Northrend its about 500mb used.

ANYWHERE else in Outlands or Azeroth its about 400mb used.

Dalaran actually causes my system to start paging memory to HDD at times. Its f'in horrible. Running multiple WoW's on one box? /shudder. Make sure you've got like 6GB+ of ram. I'd probably vote for 8 honestly.
Fur has it spot on.

I had to upgrade to 8 gigs of ram so I could walk around. I am finally able to crank the graphics and walk around just fine. Thank god!
