I am both NZ and TX -- my parents were in New Zealand when I was born, so I could emigrate to there if I chose to do so, and not have to fit into any quotas. But my folks were Texans, and they brought me back here before I was old enough to have any memories of that down-under land.
About the differences in NF7's, the S2's do not have the MCP-T, nor do they have the flexible options for overclocking activity. I was hoping to use the Gigabyte LAN to bridge between a very small LAN and a much bigger one, and I thought I'd be at a disadvantage with the slower ethernet twisted pair NIC's in use on the small one. I ended up with just a switch between the two LANs; the NF7-S2G that I tried had several problems and I never did get any kind of LAN running to the particular PC involved while that MB was in it.
