Will I have slowdowns in a lot of areas like gaming and video? My 1.8Ghz PM(single) with an X800XT is holding up just fine on 720p video, but how will I get 24fps on 1080i? I am only getting about 10-18 there. Also is there anyway into tricking my 19inch right now to go up to 1920 by 1200 to test how the games work at that high of a res? And do games like Halo and BF1942 go up that high in res?
