Hey fellas.
I was mining yesterday with guiminer at slush's pool and I got the average 80mhash/s. My GPU was at ~85 ºC at 100% fan speed (1800 rpm). My fan is an Evercool Buffalo and my GPU is not overclocked: 750mhz gpu clock and 900mhz memory clock. I got like 16 shares in 15~25 minutes, is it good?
Is it worth mining in these conditions?
