Hmmmmmmm. That seems awfully low. I would definetly call them and ask. Sounds to me that that's just a 5800 normal and not an Ultra. Something just seems fishy with an Ultra 5800 being priced that low.
I've talked to a couple of retail vendors and (their cost) isn't even that low for a retail boxed card. If they are legit then that's a steal and a half. But I would definetly call first...
