CPU Bottlenecking

[Ashrym]

I have a P4 2.66 ghz/Asus P4C800 Deluxe Mobo. Which range of graphics cards will I start to see my CPU bottleneck at? I was thinking about going with and AGP X800GTO/GTO 2.

An X800 series card should be fine. Bottlenecks don't really occur until you start going for very high end like a nVidia's GF7800+ or ATi's X1800+ series card.

EDIT: Make sure that the AGP GTO cards can flash and unlock, as far as I know it's only the PCI-E cards that can do this. If this is the case you should consider something like a 6800GS.
