More memory. Get 4 gigs.

Figure yeh got Xp look into setting it up for performance.

I run a p4 3ghz its one of does cheesy dell boxes 240 something or another with 2 gigs or memory and some ratty graphics card damned if I remember what it is at the moment. With all the setting reduced to lowest possible I can run 3 thru a major city with some patiences and 4 in an instance.
