I recently paid $125 for the last MSI Gaming 5 so that was a steal. It replaced the user's originally planned Asus Hero ($208) which doesn't quite measure up to the G5 in features, component quality, performance as well as number of extremely negative (1 egg) newegg user reviews (the Hero has almost double the MSI .... Asus has an easier BIOS tho.
If the USB 3.1 grabs you, it might be a reason to vet the G6 but it's not as if there exists anything to plug into it. Gigabyte's Z97X is beastly with their high quality 12 phase power supply, but their BIOS I find a bit of a struggle to work in. My son recently did Gigabyte SOC Force board and it's been a great performer . The separation between the 2 GFX cards is great.
Although admittedly ASrock has improved greatly, and it's been quite a while since I have had an issue (1156 socket board) .... I'm still bearing a grudge from the budget build experiences from days gone by ... thin / warped boards, bulging / leaking caps and 1-2 year warrantees.
