Try and find out. :)

Yes, the older ones have a problem where a bus-master DMA transfer
crosses a page boundary may get corrupted. The more recent SRM versions
include a whitelist of known-good devices, and will refuse to boot if an
unknown card is found in an affected slot (though there is an override).
The slots behind the PCI-PCI bridge have DMA transactions split on page
boundaries anyway, so those are not affected.

60fps could simply be the vertical refresh rate.
