Thanks. But just for the sake of curiosity, will I7s and opterons also run dcs well? Because I am jumping between building a capabile Desktop with I5 or a barebook with I7 or Opteron. (I already have an I5-m520 and it doesn't run well and I am much of a mobile user. I just don't want to spend over $1000 with alienwares and qosimos, I at least want 1440*900 with 60fps, even on lowest settings)
