Hi Folks, My Dad's got a 400MHz Sawtooth. I've been looking over the requirements for Quartz Extreme on Jaguar. From apple's site, it's clear what the requirements are: Requirements: Quartz Extreme functionality is supported by the following video GPUs: NVIDIA GeForce2 MX, GeForce3, GeForce4 MX, or GeForce4 Ti or any AGP-based ATI RADEON GPU. A minimum of 16MB VRAM is required. Fortunately, the Sawtooth comes with an AGP slot, even if it is only 2X. However, the graphics card currently installed in the computre is an ATI RAGE 128. The 16MB VRAM requirement is filled, however, the GPU is clearly not a RADEON, or any of the nVidia cards specified above. So, my question is what is the cheapest GPU that is supported by Quartz Extreme and will work with a 2X AGP? I didn't notice any clear documentation on either nVidia or ATI's site that specified that the cards would work in a 2X slot. I am aware that Jaguar will work with or without the upgraded GPU, and that Quartz Extreme is just one feature of Jaguar that will increase the speed. So, I'll install Jaguar either way. I'm just hoping that maybe there's a $100 card out there that will work. Seeing as he's no gamer, he doesn't need the latest and greatest, just something to make the interface snappier. Thanks.
