CPU Mining with Geth. At Frontier, the first release of Ethereum, you'll just need a) a GPU and b) an Ethereum client, Geth. CPU mining will be possible but too inefficient to hold any value. At the moment, Geth only includes a CPU miner, and the team is testing a GPU miner branch, but this won't be part of Frontier. The C++ implementation of Ethereum also offers a GPU miner, both as part of Eth (its CLI), AlethZero (its GUI) and EthMiner (the standalone miner).
The Ethereum clients automatically purchase gas for your Ether in the amount you specify as your maximum expenditure for the transaction. The Ethereum protocol charges a fee per computational step that is executed in a contract or transaction to prevent deliberate attacks and abuse on the Ethereum network. Every transaction is required to include a gas limit and a fee that it is willing to pay per gas.
