Testing speed of ethernet adapter

I recently won a "Killer2100" PCIex ethernet card made by BigFoot Networks in an online contest. I'm not a big online gamer, so I don't really think I need it, and a guy I know might want to buy it. However, he isn't an online gamer either, but he is a big-time online stock trader and feels that the Killer2100 might help him with his trades. How can I test the difference in speed between a standard 10/100/1000 ethernet adapter (most likely an on-board NIC) and the Killer2100? If I can show him a significant speed increase, he'll probably buy the card from me. The Killer2100 from BigFoot is mainly aimed at the online gaming market, so I have no idea if it will help with the scenario I've described. Any thoughts, tips, suggestions, or whatever will be GREATLY appreciated! Or - if you want to buy the card, send me a PM! LOL

(I'm pretty sure a standard run at speedtest-dot-net or some other online download speed tester is not going to show any real differences)

I'm not very experienced with this, but I could offer you an option, you could try benchmarking both of your cards and comparing the results, like I said I'm not very experienced with this, you could try that but I'd say get a 2nd opinion on it.

Speedtesting them isn't going to make much of adifference-still only going to show your current internet speed.
Only thing I can think of is
1) show him http://www.bigfootnetworks.com/killer/2100-datasheet.pdf

or
2)
Get a pair of them, time a transfer of a large file accross it, and time a transfer accross a standard card?

 

@ Groinsh0t: I was pretty much planning to the same thing.... can I use something like Simple Internet Meter to log the actual speeds of a file transfer? Or will this simply record the same thing that a std speed test will? I know there's a tool out there to record/monitor latencies, but I don't think that makes a difference in this scenario. The Bigfoot card has me a bit confused, because your internet connection is only as fast as it is, ya know? I don't really understand how one 10/100/1000 card can be "faster" than another 10/100/1000 card. I've read all the literature at the Bigfoot site, and while it makes sense, I'm still just a bit confused.... I guess the Bigfoot card processes the data from the web faster? Or it's designed to process certain types of data with a particular 'signature' faster?

 

I really don't know what the advantage of the card could be, the fact that it is a 1000Mb card is enough of a reason for it to be considered high performance.
Actually, latencies etc is exactly what makes a difference in this scenario... Higher latency means less responsive games...
