p4 3.0ghz processor with hyper threading.
3g of ram
256mb graphics card

Runs 5 wows just fine, with some of them resized to be smaller so I can see them all. I do get choppy in populated areas at times though. Even works when my virus scanner does its weekly. CPU is usually in the 90s when I check, and I usually have about .8-.9gb of free ram.
