could anybody help please? also, any knowledgeable person who would be willing to help me in private chat with a few bitcoin related problems such as ::
1. how do i buy a bitcoin, ive tried online and it seems very difficult. Id like to convert the 300$ cash sitting in my wallet into 2 bitcoins. plz halp!
2. talk me through what type of mining rig i should build (i know more about computers and computer hardware than bitcoins, im not as dumb as i sound.)
3. how long it will take for my initial investment to pay off, and if i invest slightly more will it payoff faster -- thanks in advance!

do you have stratum changed to yes?

For a rig buy AMD 7950s and I would say 4 GBs of RAM and a cheap processor. Use CGMiner. Get PCI-Express Risers to separate the cards or else they will get hotter next to each other. For example my motherboard has 3 side by side PCI-Express slots. When the cards are seperated I get ~67c per card with the fan at 54% when I don't use risers I get 75C

To buy bitcoins transfer money to btce https://btc-e.com/ using a service in the finances panel after signing up and the buying is straightforward right on the home page, type in how many you want to buy.


3x 7950s would be roughly 750 watts to 800 Watts including everything used for a PC except for a screen. They hash at an average of 550 x 3 hashes with LTC and lets say .14c a Kh/s = $167.34 profit a month after paying electricity, this is the same for LTC and BTC.
Dont forget to join a mining pool and they usually have a pool fee of 1%-5%
