Some problems with v10. With i5 CPU and 3 280x everything works fine, I get 16 CPD. But with AMD Sempron single core processor and 3 280x very few share only found. It estimates 15 CPD but reality is more like 1.5 with 10.0v. Same rig estimates and averages 14 CPD with 9.1, so I switched back to 9.1v.
