I ran a xps 410 wit a e6600 2.4ghz and 2gb ddr2 667 and the ati x1300 pro and could run 2 wows okish and 3 was killing me. Bumped the ram to 4 gigs of 800 and then a ati hd3450 sb edition and could run 3 with out a problem. Only time that it sucks is in heavy aoes and in major cities. But did do the job for 3 after the up grades. Hope this helps
