It was only released around a week ago, probably why no-one has one. Basicaly it's the same chip as the 6300 but with the extra cache.
I think the board would be fine, with 2 cards you'd still have a pci slot between them and the gfx card. Why would you be using a network card though?
Couldn't really comment on if the deluxe was worth the extra though, I've never used either board.
