My G4/400 Sawtooth still has the original ATI Rage 128 video card in the video slot. In some games such as "Medal Of Honor" , certain of the fast graphics intensive sequences, are very "draggy". For the most part the rest of the game plays fine even with the graphics options "turned up to max". Even when I make adjustments on the video options screen to reduce the load on the card the system drags in the fast sequences. Now I know that the Aspyr recommends the G4/450 as the minimum required configuration, but so far my old soldier has been quite adequate for it. Two questions: My question is: would installing an ATI 8500 make any improvement over the the stock card for gaming, or am I being limited by the main CPU processor clock? How can I determine which is limiting? If I choose to upgrade to a GeForce4Titanium will it operate in my 2X AGP slot. The tech spec are a little above my heat but I've an idea thaat the 2X card may not have enough power feed for the card. Is that right? Thanks, John
