I've got it hooked up to an Xsurf3 card.
The A3640 came in today - dead :/ I threw it into the 3000 and was greeted with a nice black screen. Though I asked for a 3.1 card, I might have gotten a 3.0. 3.0 is silkscreened on the card, and there is a "3.0" sticker on the back. In one little type written sticker it states "3.1" on the front. I'm asking for an exchange...
