If potential support for PowerMac11,2 won't span over all models, I'd prefer the slower dual-core ones to the quad-core one, because I prefer air cooling over liquid cooling.

...or have been supported since MorphOS 3.8 already, which added compatibility with Sam460 and Radeon R500 (2D+3D). In a PCIe-capable MorphOS machine, I would take a 3D-supported R500 card over any 2D-only supported higher card any day. But that's just me :-)
