Exactly. To do it with one card you would need to find a card that had two complete sets of hardware on it. I'm not sure such a card exists but if it does it's probably far far more expensive. Hence my '100x' guess. Regular single radio cards can be had for <$5.

Thanks again Derelict for your valuable insights I did see the Startech cards when I was searching for a good fit, and I am now ruing that I didn't order one. It looks like I have done my dough $$$ on the card I now have... Your are absolutely correct - I didn't think it would be so hard to get things working. This was supposed to be my cheap and economical to run setup. I have a second machine with a Core i5 2500 (95W) that just chews the gas, but the MB has all the goodies integrated... Looks like it's back to the drawing board lol
