Unfortunately, the other motherboards were not available for UT2004 tests. From the looks of things, you probably won't want to use this integrated videocard to play UT2004... it's just not powerful enough. Luckily, with that 8X AGP slot you can upgrade to a Radeon 9800XT or equivalent videocard easily enough.
