In keeping with the speed increase, the graphics slot has been doubled in speed. The PCI slot for the graphics adaptor now runs at 66 MHz, yielding a maximum throughput of 264 MByte/sec. This provides comparable speed to the AGP 1X slot.
From previous experience, this bus speed has been sufficient to run 1280x1024 Open GL 2D/3D graphics @ 60 Hz with no issues using the ATI Radeon 9700 series and above graphics cards.
Am I missing something here? "Radeon 9700 and above" isn't available in PCI format...?
