I am looking at this. Dual FPGA X6500 Mining Card Rev 3 (Without Heatsinks)

So we connect the card via USB and the card will mine?

Should I buy one FPGA or several ones? Where do I attach the FPGA? PCI? USB?

  • I think ~$600 for 400MH/s is not the best deal. Myself, I'm waiting for these to show up (although it's not sure if they are real or just nonsense), they offer 3.5GH/s for $149: news.yahoo.com/… Jun 23 '12 at 8:48

    100% nonsense. BFL have a very bad reputation for never shipping products on time and over-estimating performance. It also makes no financial sense why they would price the product that cheaply. Jun 23 '12 at 12:29

    I don't think you should ask "how many should I buy" questions on SE. Please review your question to be non-personal and objective. You branch a bit too much from the title of your question.

From what I know, you can connect basically any amount of FPGA cards to one computer through USB hubs. Case in point:

    An operating system may have limits. With USB, a driver may be needed to address devices beyond nine. Some hardware requires (or benefits from ) drivers too. Jun 23 '12 at 18:03
