Hey guys I'm mining with GUIMiner on Slush's pool with 2 GTX 980s. Both watercooled and overclocked.

The 1st GPU is fine, but the 2nd one is running on very low speeds.

Put them at stock clocks. I hear that fixes it for some people. Also make sure your using the latest Nvidia drivers. 

 eGPU Setup: Macbook Pro 13" 16GB DDR3 RAM, 512GB SSD, i5 3210M, GTX 980 eGPU

Also another thing, It seems like the 1st GPU (worker) started runs a lot faster than the 2nd one. Or there's some sort of barrier at around 715-725 Mhash/s

wow 980's get 700+ MH/s ? Nvidia has come a long way in mining performance lol

 

but mining isnt profitable anymore for GPU's. That ended years ago. mining is a rich mans game now, only expensive ASIC's that u get on day 1 of release will actually profit.

Yeah they have haha. And I don't mine 24/7 with my GPUs, just comparing with my previous 290x.
