Examine Checkbook Balance (CB) Place finger on CPU List in Catalog Move finger over prices, get as close to (CB) above as you can without going over But seriously, there are *so* factors involved, including what it is you want to do with your machine, that it's virtually impossible to reduce this sort of thing down to a formula. "What you want to do" is perhaps the hardest thing to figure out, but I can guarantee one thing: It will be quite different from what you thought in the first place. Nobody ever complained about having too much CPU, or RAM, I'd go for the best I could afford. _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
