For those of you that have Vega hashing at a high rate can I ask what Motherboard and CPU combo you are running?

I have tried two different motherboards (TB250-BTC, Asus Z270-P) and have not managed to get more than 1350 H/s.
Both motherboards I have tried were running Kabylake CPUs (G3950, G4560).

Thinking of trying out a Skylake processor in case there is an issue with Kabylake and Vega.

Thanks
