Gain, I meant PCI-E. What concerns me is that I recall the struggles Linux went through to get agpgart support working and I am tad concerned about how PCI-E is related to the agpgart code in the Linux kernel. That is does the fglrx kernel extension just consider PCI-E as a varient of AGP? I know I can get around 2000 fps in glxgears with a Radeon 9600-XT card on AGP-8x and want to make sure that the same level of speed boost will be available from the fglrx driver when using a Radeon X800 Pro on PCI-E. I've not had any luck in finding a discussion of what the equivalent for drivers/char/agp is for PCI-E in the linux kernel. Jack
