My main is about the same Kal, a bit beefier..
Athlon 2000+ 768MB of Ram, GF4 4400, WinXP... etc
and I have no issues using EQW in 1024X768 with a screen rez of 12X10
/shrug. Could be that I keep my page file on another physical drive or that I keep my machine defragged often.
I am also running Norton AV as well.
