Mining Bitcoins with XFX HD 7950 Core Edition 800MHz 3GB DDR5

Mining bitcoins? This graphic card is a good choice for a good price. Is capable of 450MH/s and probably more if is overclocked. Down bellow I will list other other graphic cards what are not necessarlly cheaper, but are better that 7950. Note: I didn't test the graphic card myself, but according to Mining hardware comparison this are the values what you should expect from it.
