I understand that the latest PowerMac G5 have PCI-express. The question is, will I need it? I want to have the G5 as a gaming machine for all my PowerPC 3D stuff and as a general working machine with a nice 2_" TFT display.

The better graphics cards available are PCIe rather than AGP (which the PCI/PCI-X PowerMacs had).

Thanks, I had actually forgotten AGP at that moment. So the fastest reasonable ATI gamer cards for the G5 would be:
AGP: Radeon X800 XT
PCIe: ATI Radeon 1900XT

Would NVIDIA be better / cheaper in any way (always had ATI cards)?

The best AGP card for most uses is the X800. I don't know much about the PCIe cards. As for the choice between the two, other than MHz it depends if you believe compatible PCI cards are more plentiful on the PCI-X side or the PCIe side. I also recommend going for the non-liquid cooled models, either the 2.0 (AGP) or the 2.3 (PCIe). They're great Macs. I just installed two additional GB and an ESATA card in mine.

Well, there are two (?) generations of graphic cores between the two. My guess is, for gaming the X800 masters everything but the last generation in high resolution / FSAA, whereas the X1900 will master everything.

I agree about the liquid version (that was only one the old DP 2.5, right?). It's a shame I can't get an DP 2.7 or an DP2.5 with PCIe. DP DC 2.5 would be overkill, I guess.
