It really is a tragedy that Apple abandoned the Cheesegrater v1 for the Trashcan.
The modern iteration of the Pro Macs (really, Mac Studio for most people) probably the best that can reasonably be expected of Apple. But the continued feud with NVidia is really unfortunate.
Although I suppose the Mac Pro doesn't really support graphics cards in its PCI-X slots anyhow. Or at least that's what I recall.
