help needed with building a pc

Put it this way, the X1950Pro is about 20% slower than my card. Up until about 6 months ago I could play almost every game out there on max settings at at least 1920x1200, if not 2560x1600. Since a 19" screen will be limited to either 1280x1024 or 1440x900 resolution, you'll have no trouble running pretty much any game except crysis on at least high settings, if not max. Of course in time that'll change, but for now the X1950pro isn't a bad card, Provided that you have a decent version. There were some pretty bad versions of the X1950Pro made, some decent ones too, but if he has a Powercolor or Gecube version, expect issues. Usually though they were so bad you would have heard about them already.
