Enable quartz extreme?

I recently got a new PCI graphics card for my powermac AGP ( I know, it sounds weird, a PCI graphics card for an AGP model? Apparently, my AGP slot isn't fast enough for the new ATI AGP cards, it's only 2x AGP, and i need 4x or 8x)
But anyways, I was surprised that quartz extreme was till not enabled. I have 128 mb of VRAM, so I think that I have the power to.. I tried a program that enables Q.E., but it doesn't work. Am I stuck with a non-QE machine? Are there any new AGP that will work with my computer? Is their any way to enable quartz extreme? Thanks in advance.

No QE Under Tiger

Quartz Xtreme has been disabled under Tiger because it is too buggy. Bad news, I know, but Tiger handles video differently so even though you might not get the "cube" effect with faster user switching I think you'll find it quite good enough!

In addition, Quartz Extreme is only supported on the AGP bus.

Just about any AGP card will be faster than the fastest PCI cards. PCI is extremely slow compared to AGP, no matter how much VRAM the card has.

that's actually wrong. Quartz Extreme has been enabled since it was part of 10.2 Jaguar.

Quartz *2D* Extreme is still turned off by default, and was a feature of 10.4 Tiger.

Well, are their any new cards that will work in an AGP 2x slot?

There's this monster, which would absolutely rock in that system:

A bit pricey, but it's only about twice as much as the PCI card for MUCH better performance.

Wow - thats expensive. But I wonder if I can justify it. Will this help with rendering times, burning DVD's, and other multimedia work, or will it just quicken up games and the mac os x "eye candy"?

And how many times better is AGP than PCI, would a 128 VRAM AGP card be equivalent to a 256 PCI card?
