There is no point mining Bitcoin with video cards nowadays.
I personally have created small righ 2 x 7970 for mining litecoins. At current prices a have small profit at about 40-60$ a month.
And i hope soon litecoins to be included in some better exchange markets so i can hit good.
If you are goonna do, be sure to made good calculation of electricity, heat and so on.
@@ Keep calm and keep mining
