So if you have, for example, a rotating star as a particle then Vertex Buffers won't help?
However, if you have a non-rotating particle where the vertices (?) do not change but it's draw position does then they CAN speed things up.
I think colour is passed in the vertex information (is that right?) so a colour changing particle would negate the effect. Would that also include alpha?
<edit> If that is all true then Vertex Buffers seem to be of limited use for Particles however fast. So...
Is there a DX version of Vertex Arrays?
Can Vertex Arrays be done with native Bmax commands?
