Getting the MSI 790FX-GD70 would be a better choice in my opinion as compared to the asus board the msi one is able to go quad cross-fire with dual slot cards unlike the asus model as its slots are aligned differently and the layout of the I/O ports along with the variety like firewire and 2 LAN ports are better in comparison with the asus board and its sata ports are also laid out better compared to the asus. Finally the features are similar along with overclocking with the dials other than asus having a slight lead in overclocking however the MSI board requires a bios update for stability, after that its fine. Overall for the price, features and overall layout for the board I found the MSI board better compared to the asus one.
Sorry for the long post.
