I was told on OcUK you never get the full 100Mbps throughput on a 100Mbps NIC for the reasons I stated earlier. So instead of just being patronising why not explain the reasons in your reply? I'm all ears.
EDIT: Re-reading my earlier post perhaps I should have been (rather) clearer. I meant connecting through a gigabit router with a NIC set at 100Mbps. I obviously realise NAT doesn't exist on a NIC or switch, but rather that a NIC connected at 100Mbps to a gigabit router with a high speed WAN (i.e. >100Mbps) would not pull the full 100Mbps. If you'd care to explain where the 'missing' ~5Mbps goes to give a maximum throughput of ~95Mbps I'd love to hear it. There's no need to be rude.

Overheads, just not the overheads you mentioned. Qas can probably explain it in better detail than I can, but the data being transferred has to be wrapped into packets (At the TCP/IP level) and frames (at the Ethernet level). Think about it like sending a letter through the post - you can't just shove it in a letter box, you have pop it in an enveloper which will add a small amount of weight to the thing. You also need to write the address on it and when it comes to communication, the address of the receiving machine also takes up precious bytes. That all adds up.
You're right about 96Mbps being a reasonable real world maximum when using a 100Mbit router, but OP said himself that he's happy with the current performance he has:

The only things I have wireless are a laptop (a lenovo s400 ideapad) and a Android Moto G phone, both of which are getting about 50MB wireless according to speed tests, bit of a coincidence. I suspect the Moto G wouldn't take any more anyway and I don't need anymore on it. The laptop will get the same 94MB if I wire it up and 50 MB wireless. The wireless network adapter on it is an IntelCentrino (R) Wireless - N2230, so not sure if thats capable of 5Ghz.
tbh I wasn't really looking for a speed upgrade anyway but 100 worked out cheaper than 50MB when renegotiating my package for some bizarre reason.
Will probably stick with the Netgear N150 router for now (what wireless speed should it be capable of in the real world ?)

And indeed, it's not worth spending any amount of money for the sake of 3-4Mbit. In all likelihood, OP's PC's are gigabit anyway, so if/when he upgrades his router he'll probably see his PC's sync at 1Gbit regardless.
