Dual Port Gigabit NIC recommendation for XG, preferably from Ebay (PCIe)

Question

Hi. I'm building a new home firewall, as my existing one is very slow already. I'd like to use parts off ebay, to make it cheaper. I have always read that Realtek NICs are no good, and should use Intel Gigabit NIC instead. 
 Any known working NIC for PCIe interface?

Hello jang430, 
 It should not matter if you have a Gigabit switch and your ISP connection is lower than that, the connection made by each PC will use your your available bandwidth. Since you are going to use Sophos, you can regulate the traffic via QOS policy implementation.
