just received my 5500 pci today, and I ofcourse benchmarked it right away on the XP2400 rig.
Score for 3dmark99 is 7473, almost the same as the agp part, which was to be expected.
It also had 33910 cpu marks. LOL
Strange thing was tho, that I scored 7473 with the PCI card and XP2400, where I scored 7535 with the AGP card and XP1800, so I'm gonna do some more benching.
But as it looks now, I'd have to say that the 5500 PCI is running on max what the pci bus can do.
Gonna do some cross testing to verify this.
XP1800 + 5500 PCI 3dmark99: 7426
XP1800 + 5500 AGP 3dmark99: 7539
XP1800 + 5500 PCI 3dmark2000: 4882
XP1800 + 5500 AGP 3dmark2000: 5597
XP1800 + 5500 PCI 3dmark2001: 2335
XP1800 + 5500 AGP 3dmark2001: 2834
seems pci really is limiting scores.
