GTX 1070 Asus ROG Strix OC on cheap mobo ?



Is it actually a decent motherboard ? I had bought it for $110 CAD, which would be under $100 in US (which i thought meant = low end). I have a i5-4460. I know it's a huge bottleneck with the GTX 1070, but in 2 months i can afford the rest my planned upgrades: i7 6700k, MSI gaming M7, Corsair H115i, and 16GB DDR4.
By the way, thanks for the answer.
 


I get 100% usage on my CPU on some games while my GPU is under 70% sometimes. Games that come to mind are H1Z1, Battlefield 1, and Starcraft 2.
