Well I am using a 3930k + X79 which isn't exactly energy efficient.
Idle power usage is 165W. With a single GPU it is around 360W - 400W depending on the WU. Both GPUs together are around 500-550W. Everything around 600-650W.
With the 8900 WU I am getting about 140K out of a GTX780. Can't wait to watercool them as in my setup they are directly next to each other and running hot and loud. Should be able to get significantly higher clocks on water.
" Dr. Peter Venkman: Ray, pretend for a moment that I don't know anything about metallurgy, engineering, or physics, and just tell me what the hell is going on. ! "
I get between 25-35 kppd per Nvidia 580 , depending on unit.
Does this seem accurate ?
Or is it that I just really need new video cards ?
Seems low to me. I am seeing 45-60 depending on wu on a 580. I have seen 45 on a 560 ti 448 core as well. Mind you I am using core 17 and have some cores on the cpu turned off. I also have client-type and beta flagged for the gpu's.
