If you have two network Chips intergrated on the Mainboard can you set one as Send Full Duplex and the other one as Receive Full Duplex? Thats would be double the bandwith as using one as full duplex. I just thought of that when I read different reviews of SLI or Crossfire. How fast would 2 Killer Nic Cards be in a combined duel mode? They cost around $150-$200 almost expensive as a GPU card and the Same Price as an Ageia Physx PPU!
