Actually it depends on the motherboard chipset. Some chipsets allocate 
an interrupt per slot, and when you have lot's a traffic between two 
ports on a dual port card the will increase dramatically, but should get 
you at 1Gbps, at higer speeds... depends.

It's adviseable to use a 2.6 kernel as the network stack, compared to 
2.4, is way better and you can achieve higher speeds.
