envy in silence and prove that you can do it better

8*6990 would have been godly for mining

It will give 5.1 * 8 TFlops = 40.8 TFlops, 5,28 GHash/s

the whole network is 580 GHash/s - bitcoincharts.com

10 500 000 BTC per 4 years = ~7200 BTC/Day

7200 * 5,28/586 = 64 BTC / day

~220 days to cover costs (without electricity)

If only this can work without overheating in first couple of minutes, it would be ~4.32 GH/s. (8 x 5970)

~55.7074180016 BTC per day at next difficulty (after tomorrow).

Let's assume that difficulty will increase by 30% every 10 days for easy counting.

557 + 340 + 273 = 1170 BTC first month

190 + 133 + 94 = 417 BTC first month

66 + 46 + 32 = 144 BTC third month.

8 * 300 = 2.4 kW just for the cards * 24 * 30.5 * $0.1 = $175 per month for power, oops, we are not profitable already.
