If a card is supported, it shouldn't matter if it is AGP or PCIe, just as
with older cards, it does not matter if they are PCI or AGP.
I know that 2D is supported. The question was 3D. For some time, the R300
and newer chips were 2D only and then support for 3D was available.
I have not really heard anything about using FireGL cards, but if they
use the same chips as the consumer cards, I guess they should work.
http://dri.freedesktop.org/wiki/ATIRadeon is probably the best place
to see what is supported.
I've been there, but might be out of date (I did notice the last change
date). They list R300 and above cards as not well supported for 3D. I don't
know if that means that it might or might not work, but the FireGL X1 seems
to be fairly well supported for what I've been doing with it (which is based
on the Radeon 9700 R300 chip).
I was looking at a V5100 or V7100 (both based on the X800 or X850 chip).
But the question remains, is the R4xx chips supported in 3D?
Yes R300 and R400 ATI GPUs have 2D and 3D support with the OS driver,
unlike the R200 series this was achieved through reverse engineering and
the support is apparently a little less complete as a result. However
there are rumors that ATI will open up specs to their older GPUs as well
as the newer ones, and even if they don't, their is an expectation that
knowledge trickle down will occur from the development of the RadeonHD
driver, either way, R300 and R400 support (currently very good anyway)
will improve further.
AMD recently began releasing specs for ATI cards, and is working
with Open Source devs to create good drivers for all modern ATI
card, but it will be a while before there are results for end users.
I read this and was quite pleased to hear it.
I appreciate your response and any help you or anyone else reading can give.
The easiest to get hold of, best supported, cheapest, ATI, PCIe graphics
card at the moment is the Radeon X1050 which, despite the odd marketing
gimmick R500 style name, is in fact an R300 card, and I have 3 R300
systems at the moment so can recommend that GPU, though if I could've
got a R300/R400 card with dual DVI, I'd've payed extra for that.
Having said that the only reason I upgraded from RV280s is because of
the 1536 pixel width limit on overlay on that GPU so I'm not a big 3D user.
Good luck
