Is glEnableClientState the right way to process vertex buffers or is this an archaic method.

As long as you use glBindBufferARB and glBufferDataARB (ARB_vertex_buffer_object) with it, it should be fine. If not, you aren't using vertex buffer objects, but just vertex arrays, which results in sending vertex data to GPU every frame (vertex buffer objects allow you to store it once and use every frame without any additional overhead).

Thanks
