Im making a NAS and a pfsense router so I need 2 cheap nics. 2 Ports + each would be nice. Im in Australia and the budget is around $100< each AUD. These are some I have found.

The second listing is for a Pci-X adapter which is an old standard that was really only on servers, and I highly doubt a new build would have a Pci-X slot. Its somewhat ancient in computer terms, lol.
The First listing is solid. Intel Pro-1000 cards are great, I have three now, all of them rock solid. I use one in my desktop, one in my nas, and one in my PfSense box. All are rock solid, no problems A+.
The Third listing is an intel I350 chipset, so the more servery chipset. Definitely not a bad choice, but neither is the Intel Pro-1000 card (the pcie one :). It really comes down to if you want to spend for the extra 2 ports. You can't go wrong with either the I350 card or the Pro-1000, its just all on the money you want to pay out :)
Do you think ill need a nic for a NAS? http://au.pcpartpicker.com/product/tDphP6/msi-motherboard-h97me35 thats the MOBO
That board has a Realtek 8111G, so not a terrible Nic by any means, but Intel reigns supreme. That being said, unless you plan on constantly saturating a gigabit link to the nas, its probably fine. If you plan on hitting this thing hard and with very consistent gigabit clients, it wouldn't hurt to grab an Intel Nic, but your probably fine without one. Plus, if you do find you want a little edge more network performance in future, adding a nic to your system is about as easy as it gets and is very painless.
Ill probably just have no nic for the NAS then if I need to ill upgrade later.
Not a bad plan at all, chances are you'll have no troubles :)
