Hi I'm new as well, glad to join the forum, just hope reading and posting here will de-mystify bitcoin and avoid and pittfalls.

Hopefully, well thanks anyway for the assistance.

Sorry my apologize I was referring to the 5770 model,

I had some questions about m/hash,  and energy usage, ATi Radeon HD 5700, OS windows 7, and I'm clocking in at 130 m/hash. I thought maybe a downgrade to xp might help improve performance, or perhaps I just need a new graphics card,  if that's the case any suggestion for a low energy mining card? And what else can do to improve my m/hash rate  and what determines m/hash rates?

I'm running Amd Athlon II 450 x3 , which clocks in at 3.2 GHZ, ATi Radeon HD 5700, OS windows 7, clocking in at 130 m/hash. I don't know seems a little low, what precisely determines your hash rate anyway?
