As of now, AGP 8x is just hype and not really needed yet. The performance from AGP 1x-2x-4x is minimal and it will be even less for going to 8x. Now this doesn't mean that sometime in the future it will become necessary with the larger textures being pushed through the pipes, but right now the bandwidth for AGP 4x is plenty. Plus, if you get a mobo with AGP 8x, then the only way you can benefit is by actually buying a vid card with AGP 8x and I don't see any of them available right now.
