Yes it is definitely easier to buy a real heater. The calculation is also wrong, because GPU produce heat only as a (conceptually unwanted) by-product, while the heater produces heat as its main product. So GPU heat production per Watt is not comparable at all to a heater.

You might want to revise your numbers a bit.
You won't be running your heater at 100% capacity 24 hours a day.

Let's travel deeper.
1. Figure the actual percentage of wattage released into the air from a GPU.
EDIT: 6990's are rated at 375watts TDP; TDP is defined as the amount of energy the cooling system needs to remove from the IC for proper functioning http://en.wikipedia.org/wiki/Thermal_design_power. So I would have to figure it would dissipate 375watts into the air at 100% PU usage.
2. Possible duty cycle of GPU heating system to keep house warm and not cook humanz alive.
3. Duty cycle will give us the cost of electricity
4. Duty cycle also gives us potential coins generated
5. Subtract electricity cost from coin value, hope its small!
(currently working on finding a good guesstimate of these)

Cant believe you actually thought about it seriously.
however, if you have $17k to spare, please do it regardless if its profitable or not just for the coolness of it.

That's why I ponder on things like this, cool things come from it. Though they never get created. Well the only thing I "created" from an idea like this was putting dry ice directly on my GPU PCB+IC one day, it was sweet. Still have the card and it works
