Jack:
    At this point I can tell you that pretty much all PCI-E cards from 
ATi in the market are reasonably well supported by the latest driver 
(8.8.25) in Linux. You can expect pretty much the same performance 
difference compared with an AGP card with and without Direct Rendering 
on your PCI-E. However PCI-E implementation is two fold dependant: It 
depends on the driver end and it depends on the kernel end to provide 
support for the interface on the system bus (though I think as with 
AGPGART, the graphics driver is capable of providing this too, like the 
internal or external AGP driver in fglrx).

My other comments regarding performance were mainly when you compare the 
Windows Vs Linux performance of ATi hardware, which obviously is due to 
drivers... I'm confident, though, that in a reasonable amount of time, 
now that ATi has started to gather momentum, ATi will have pretty good 
drivers with impressive IQ and paralleled performance...
