I've read a bunch of reviews on this thing and it seems like it's worth getting, but i don't want to add on $250 to my rig. How much performance increase would it be over the onboard connections on the evga 680i sli board i just ordered? http://www.newegg.com/Product/Product.asp?Item=N82E16813188009
Also are there other add-in network cards that would do about the same thing for a lower price?
