We're still trying to wrap our heads around the idea that an aftermarket NIC can really improve your gaming experience, but time and time again Bigfoot Networks Killer
line of network interface controllers comes through reviews with flying colors, and its latest, the Killer 2100, is no exception. Boot Daily
took one for a spin and found that it "completely destroys the typical on-board LAN port in all the gaming tests." Latency and UDP throughput were clearly improved, and the new software was found to be comprehensive and useful. We're still not seeing this as a product for casual gamers, but if you've ever blamed lag for your inability to rack up the headshots then this is $129 well-spent -- assuming you'll be able to come up with some other excuse.
