The Gaming 7 has these different features:
- 3 more internal sata ports
- 1 PCIe Power Connector (the gaming 5 does not have this)
- Clear CMOS Switch with LED (the gaming 5 does not have this)
- Power Switch with LED (the gaming 5 does not have this)
- Reset Switch with LED (the gaming 5 does not have this)

Other than that they are exactly the same.
