I don't know why people refuse to understand, yes there is room for improvement. No, this won't make a crap connection good. If you have never tweaked your NIC settings and OS settings this will show alot more improvement then if you've already gone through the effort of configuring your system for small packets which is a rough low latency setup. Offloading network data is already done or available by the any modern networking chip, check your settings and enable it if your concerned about your CPU cycles. Vista/Windows 7 has always been configured (M$ has stated this was their intent) with networking algorithms aimed at high bandwidth (large packet)/(relative)high latency rather than low bandwidth(small packet)/low latency. This was intentional, more people move big files that they don't care if it's 15 or 100 ms delayed than gamers that care about the small data that would have been an opponent’s demise if it sent 10 ms sooner. So the aforementioned OSs are setup to send large packets, so the OS tries to be smart and holds onto data momentarily to wrap it up in one big packet(more efficient for large amounts of data), than just send lots of smaller ones as the data arrives(less efficient but more timely which is what a gamer wants). So the nice little Killer NIC circumvents window's method (because programmers likely just use the DirectX libraries for networking) and provides more desirable method of handling your network data. Then they throw in all the bells and whistle programs to help you see it and go gee whiz. Now, you can pretty much go through any gaming network setup guide for your OS which likely turns on all the offloading options available, minimize your buffers and MTU (maximum transmission unit), and *explosion of glitter* you've arrived at very similar result as the killer NIC. It is a brute force way to manipulate windows network implementation, and is neither as elegant nor efficient as the Killer NIC. If you like the results of configuring your onboard NIC as such, you may be interested in the Killer NIC if you got money burning a hole in your pocket. Otherwise, you won't like it unless you want the pretty graphs. Either way the "extra drivers" are less than what windows is already doing poorly in terms of latency and does help if you care about getting your data out before the other guy, which the game uses to determine who shot/hit/clicked first, and that is more meaningful than the latency reduction.
