Geforce 6800 supports AGP 8x and PCIe 1.0. It will not support 4x.
Yes, it should do, but only at 4X. The video card (and it's drivers) ought to recognise the AGP's speed and will operate accordingly.
yes. but it will only run at 4x. not 8x. oh yea. get an ATI Radeon. don't wast money on that geforce garbage.
I'm sure it will, it will just run at 4X.

The voltage of that card is around 1.5 volts (the default for AGP 4x cards). [Source: PCReview UK]
Yes, but the card will only register at 4x AGP. You will not get the most out of the card with that mobo, but will still have great results.
geforce 2 gts
yes
Hi, I believe the GeForce FX5200 is a 128MB DDR video card and its compatible with an AGP 8x interface. Since I have the same motherboard, P4VXASD2, I know for a fact that this motherboard does not support the AGP 8x interface, and on the contrary, the FX5200 is a AGP 8x card and I am pretty sure it is not backwards compatible with AGP 4x which in fact is supported by your motherboard. If you are looking for a video card in the same/lower price range, I would recommend you to buy the ATI Radeon 9200/9200SE/9250 because they support upto a max. of 8x and they are also backwards compatible with the AGP 4x. I hope that answers your question.
Yes, AGP is completely backwards compatible.
Yes, at 4x speed.
At the time of writing this (11/21/2009) it's the ATI HD4670 which is available in AGP 8x format will function perfectly fine in an AGP-4x motherboard.
