Update,

My buddie Vince came over last night and started playing Call of Duty 2 with all the settings maxed out. He was playing when I went to bed and then I remember seeing him leave thru the curtains.... When I woke up I was surprized to find him in the office still playing, he couldn't stop. My room has mini-blinds not curtains so I evidently dreamed that he left but in fact he played for 10 hours straight.

I'm thrilled to finally own hardware that can run full resolution with the settings cranked.

BTW: Doom 3 is an Open GL title. nVidia cards run Open GL games much, much better than ATI cards. If Doom 3 is you thing you should look into a nVidia card. My old 6800 played Doom 3 very well.

BTW 2: When I say that the card runs with the settings maxed out I'm talking about all the settings you can find inside the game. If you go directly to the card's driver software there are some further options you can turn on like transparency aa. The 7800 card will bog down if you turn some of these advanced settings up all the way.
