Will a AGP video card work in an AGP Pro slot?
ATI: Any AGP-based ATI RADEON GPU, with 16 MB VRAM or better.
NVIDIA: NVIDIA GeForce2 MX or later, with 16 MB VRAM or better.
AGP Pro is a extention to the standard AGP connector and slot on both sides to provide additional power to an AGP card. It comes in factors, AGP Pro110 provides for 50-110W of power and requires two adjacent PCI slots for cooling. AGP Pro50 provides for 20-50W of power and requires a single adjacent PCI slot for cooling.
An AGP Pro video card will not work in an AGP slot.
An AGP video card will work in an AGP Pro slot, however the card must have a registration tab.
ATI labels their cards in the same line (9600 for example) with the standard, the pro and the XT, the 9800 has a pro and an XT model as well. XT is the highest level of the given card line.
Some appealing graphics effects, such as the "rotating cube" effect you see when using Fast User Switching to switch users, are powered by Quartz Extreme. Quartz Extreme uses OpenGL and a supported graphics card to reduce the number of onscreen calculations being performed by the CPU. To take advantage of Quartz Extreme, you need one of the following graphics cards:
Other graphics effects and optimizations in Tiger, such as the ripple effect that shows when you place a widget on Dashboard, are driven by Core Image. When a programmable GPU is present, Core Image uses the graphics card for image processing operations, freeing the CPU for other tasks. To take advantage of Core Image, you need one of the following graphics cards:
ATI Mobility Radeon 9700
ATI Radeon 9550, 9650, 9600, 9600 XT, 9800 XT, X800 XT
nVidia GeForce FX Go 5200
nVidia GeForce FX 5200 Ultra
nVidia GeForce 6800 Ultra DDL, 6800 GT DDL
