I notice many Z97 boards available at lower prices. This would improve reliability and performance, along with better onboard devices. With a "K" CPU you could also overclock. The 4690k offers better value compared to the 4790k, which tends to be quite expensive.
Your budget is $60, and I can find some relevant boards for you. Look for a mobile GPU combo if that suits your needs.
Extra usb is nice, but other than that any h61 like the p8h61mlx/le works just fine. Quality parts aren't really visible or obvious in things like VRMs—you only notice it when the CPU starts throttling. A 3470 isn't super power-hungry, so even a budget board should handle it. Same applies to overclocking unless you're doing serious overclocks like 2600+ DDR3 on an x58, where my x58a ud3r third channel completely fails and I'd really benefit from a better board like the x58a oc.
Looking up z97 motherboards yields numerous options. A 4690k CPU typically costs around $25 to $30.
Consider an LGA 1150 motherboard since those CPUs tend to hold up better and offer more value for your friend’s future needs.
