No, it's not a "bad" idea, it just doesn't add much performance right now for the money. Also it changes what parts you need, like the motherboard and psu. Don't cheap out on this part, it should be one of the top priorities. PC Power and Cooling, Seasonic, Corsair..can't go wrong with those 3. As for wattage I'm not sure how much two 8800GTX's would take to run smoothly, you might want to look into that. I think around 550-650w though would be fine though. As for motherboard, if you want SLI you're kind of limited to the evga 680i, the asus P5N32-E 680i, and a couple of others.
