If you ever wanted a heavy duty NIC for gaming and heavy duty networking. It will help speed up your gaming, and less freezing during the game. Because a lot of the cpu operations have been directly shifted to the NIC its self, thats why its called Killer NIC. The way they built this thing its as if you have a pc on your network card. If you ever build a gaming PC then this would be needed for online gaming! If Im going to build a PC any time soon, this would have to be included! hehehe!
