I wouldn't mind seeing a Klondike 4 chip board eventually. Not sure how you would power it.
The Klondike 1 appeals to people that don't have ATI video card already, but a Klondike 4 chip would appeal to people who do but are on a lower budget.
I thought you could put only 4 chips in a K16 board and it would still work? The board kits themselves don't appear to be that expensive [based on preliminary info]
