Well totaly different chipset, probably hotter running..
Generally my mobo is high 30's low 40's under 100% cpu load, when i load up everything, it can raise to 47c. Im totally not concerned about those temps, as i know the mobo can run at double that and have no issues.
Also i have the same gpu as you, the temps u say are spot on for it, i idle and load up at roughly the same temps give or take a few degree's, when its clocked at 930 core, the load is about +5c on the stock temp, but only natural for it to be.
So from the temps u say you get, i see nothing to worry about at all, so enjoy the comp, there is nothing to worry about.
