thanks,

now, you can completely ignore this if you want 'cause this thread is getting huge, but i've installed jaguar on a bunch of different macs now and have a better frame of reference as to different speeds of different graphics boards on different machines.

anyway...
the G4 dual 1Ghz with nVidia Ti 128 is plenty fast, but the ATI tv 32 i have in the PCI slot so I can run my second CRT blows. It is much slower at refreshing the screen just in the operating system.

the G4 400 with AGP2x ATI 16MB is also almost fast enough.

and even the G3 266 with onboard 2MB ATI is surprisingly fast (although it poops out at 1152x870). But the 16MB iXmicro PCI card I have in this machine is slower than snails. Unfortunately I need to use it as my main monitor card because I have to have at least 1280x1024.

Basically, once you get over the 16/32 hurdle, as long as you have AGP, I think you should be quite satisfied. The speed benefits of running both monitors off of the AGP far outway anything a PCI board could do. ( I have no idea how this would all hold up for gaming, since i don't do it) and lastly, all the PCI boards i used are old, so it's not really a fair comparison becuase the processors are probably slower on them than their AGP counterparts.
