What level of CPU usage are people getting using CGMiner 3.1.1?
I've got a Win7 x64 setup with a Core i7-3570k and getting about 25% CPU usage, hashing with just one USB Block Erupter.
I'm seeing about 60% on each of two cores. But the cpu is only runniing at 1Ghz so i don't expect much from it. running 4 erupters and a Radian 6570 GPU.
1Ghz Dual Core? never heard of such a thing.
