Doom 3 is typically dominated by Nvidia as its core design was matched for this game. Its double Z buffering for stencil shadows has always given it an edge. Both new cards do very well in this title. With antialiasing disabled, the ATI Radeon X1900XT 256 wins until 1600x1200 and beyond. The card outperforms the GeForce 7950GX2 but falls behind the GeForce 7900 cards (GTX and GT). Even at XHD gaming levels, the new ATI cards do very well. With antialiasing turned on to four times sampling it takes second place and the Radeon X1900XT 256 takes fourth.
