The Elder Scrolls IV: Oblivion
For this test, we went with Oblivion's default "ultra high quality" settings augmented with 4X antialiasing and 16X anisotropic filtering, both forced on via the cards' driver control panels. HDR lighting was enabled. We strolled around the outside of the Leyawin city wall, as show in the picture below, and recorded frame rates with FRAPS. This area has loads of vegetation, some reflective water, and some long view distances.
Even at 2560x1600 with 4X AA and 16X aniso, the 1GB GDDR4 card has only the slightest lead on the 2900 XT 512MB.
Once more, the 1GB GDDR4 card's monster memory bandwidth isn't much help.

Supreme Commander
Like many RTS and isometric-view RPGs, Supreme Commander isn't exactly easy to test well, especially with a utility like FRAPS that logs frame rates as you play. Frame rates in this game seem to hit steady plateaus at different zoom levels, complicating the task of getting meaningful, repeatable, and comparable results. For this reason, we used the game's built-in "/map perftest" option to test performance, which plays back a pre-recorded game.
I've omitted CrossFire results due to some compatibility problems with this game.
