I'm pretty sure, if you pick up any radeon class ATI PCI card you'll be in good shape.
the beauty of the 9200 is that it takes both VGA level (30) and arcade frequencies (15kz) ... if you never bother to run the games at 15khz i'm sure you'll be fine just as happy, as no matter what it'll look cooler/more authentic than on your pc monitor.
i.e. I don't think it matters all that much... but scroll down in this forum (and next page) as this disucussion has come up quite a bit...
