I paid the full price for the killer NIC card on my box, and for how much the card cost, it didnt do nearly what I hoped it would do.

As posted above, if youre a min maxer and youre dropping 3 grand + on your box anyway, might as well get it.
A thing to note. I had a problem with my linksys router and the killer nic card having problems with each other. I disabled the card on my box and I'm back to using the ethernet port on my mother board. Waste of money but oh well.

Shit happens.
