I thought it was odd too, until I asked our sales rep. The 8MB ATI chipset they used to use would have disqualified them from being "Vista Capable". So, whether we want it or not, we're getting at least 128MB of video memory on our servers now. I'd thought about trying to use it for something, but decided it wasn't worth the effort. :) -- Kevin
