Here's a review of a new NIC (Bigfoot Networks' Killer M1 NIC) with its own built-in processor to offload network processing from the main CPU. http://www.tomsguide.com/us/killer-m1-nic,review-1083.html While the target audience is gamers, I thought the network latency performance measurements comparing a system setup with and without this NIC might be of interest to those folks that are always looking to shave a few ms off their network delay: http://www.tomsguide.com/us/killer-m1-nic,review-1083-4.html
There is way more to a NIC than just the capacity to offload the stack to it's own processor. INTC makes a card for the same amount of money that is the one that is recommended. nitro
Heres a product link, same thing, but this one has one of the ports and transformers missing. http://www.intel.com/network/connectivity/products/pro1000pt_desktop_adapter.htm EDIT: Found it. http://www.intel.com/network/connectivity/products/pro1000pt_dualport_server_adapter.htm
