The 7800 can clearly handle this kind of resolution with ease - it's better suited to running 1280x960 with 2xAA and 8xAF at maximum detail (perhaps minus the soft shadows). The 6800 can actually handle 1280 with no AA and no soft shadows, or possibly 1024 for extra smoothness - if you're using a 17" TFT, you'll want the former. The 6600 is right at home at 1024, and gave us a pretty decent game experience - but for really smooth gameplay, you will want to cut out some of the high detailing (especially the soft shadows, which really are a performance killer). The 6200 with TurboCache dies at this resolution, and with a card of this class, you'll be playing at 640x480 with all the details down to low - but, crucially, you will at least be playing (and for a card that costs less than £50, that's not bad...) If the 5900 XT is representative of the last generation, including the ATI 9800 series, you'll do ok here - you might be able to squeeze in at 800x600 with low details, or 640x480 with a little bit more eye candy.
