Refer to nVIDIA's Sphere benchmarks for revealing AGP2X vs AGP4X vs AGP8X performance.
With appropriate GPU card, most applications wouldn?t saturate the AGP bus. But DOOM3(with ~512MB textures at max details) may do it i.e. needs AGP textures since most mainstream card only comes with 256MB of on board memory.

Correct on both counts. Everything I ahve quote regarding speed in my last couple of posts is in Megabytes per second. Also as covered in n article at tomshardwareguide AGP 8x is in no way noticably fqaster than AGP 4x on currect (at the time - Geforce FX and Radeon 9000 series) cards - I don't know how this realtes to newer cards, the chips maybe cabable of exploting the full potential of the bus. Also RAM and Processor speeds are a limiting factor, most peoples RAM can't shift data fast enough to satisfy the fast AGP 8x speeds.
