So far I've always used a BoundingSphere to compare against the 6 frustrum planes. It is not always so accurate, I was curious if anyone has a link to a site which explains AABB collision against the frustum.

Axis Aligned Bounding Boxes are very similar to bounding sphere collisions, the only difference is the shape, and AABB is pretty much just as cheap as a sphere, but a little more accurate, depending on the shape of the geometry contained within it.

If you just do a quick google search for AABB culling you'll get tons of hits, I just checked.
