AGP 4X/8X

Hi guys,
Here's what I'm thinking. My motherboard supports AGP, in fact I'm using it at the moment (GeForce FX5500). It's an Asus P4VP-MX and I think it supports 4X AGP, but I'm not sure.
So
1) What would an 8X AGP card do if I put it in?
2) What graphics card would you recommend?
Cheers,
Jon
