Just spotted this on the dabs web site. It looks as though it is a 9800GTX (as currently available) but with half the memory. I suspect that it is x 2 8800GT 256MB cards slapped together, as opposed to x 2 8800GT 512MB Cards.
This seems like a cracking price to me and I suspect that with x 2 of these babies in Quad SLI you will have a kick ass rig without spending uber money.
You guys can probably find it for 5p or something but I thought it was worth posting.
