Hi there. Sorry if this is the wrong area to post this but I wasn't sure where else to put it. I went out last weekend and bought myself a top of the line system specifically to play Civ 4 on. It plays great. No problems whatsoever other than minor glitches with sound on the movies. The downside to this is that it plays so great that my brother now really wants the game but his system is equipped with a Celeron 1.7 ghz. processor. If i upgrade his memory and video card, will he be able to play this game? Any advice appreciated. Thanks, Tancred.
