I have 2 x 5870 running on a rig with the cheapest one core amd processor and 2 gb of ram and a 750W power supply.
my power panel shows that i've used 460kw of power in the last 2 months. doing some calculations that means that my rig took 314W of power for every hour it was working.
this consumption is much lower than what i anticipated. the 2 cards are overclocked to 980 core and 300 memory and they make about 420 MH/s. they were up 98% of the time in this 2 months time frame.
can this be true?
