PCI Card

Installation
It's a standard PCI card, so installation took all of about 30 seconds. Even with the fancy 'K' heatsink, the card's fairly thin, so no problems putting it next to anything else.
Software installation is easy too, with the latest drivers on the disc. The setup program installs drivers, software and updates the firmware on the NIC too.
Once the drivers are in, windows picks the NIC up perfectly and everything worked like a charm.
Included Software
Configuration is done primarily through three configuration programs; 'Killer Configuration', 'Killer Firewall' and 'Killer Bandwidth Control'. Also included is 'Killer Tray Control' which gives easy access to the others from the system tray.
Killer Configuration has options for the card itself (link speed, duplex, LED status), optimizations (GameFirst to prioritise gaming traffic, buffer sizes) and an choice of game or app mode. Game mode actually bypasses the Windows Networking Stack for performance but this can cause problems with some software like VPN clients, so app mode functions just like a standard network card. Also available is an advanced configuration mode to allow you to tweak every aspect of your NIC. Sticking to the default mode, I had no troubles getting the card to work perfectly and quickly, although future excursions into the Killer forums (and the very helpful electronic manual) should equip me for a foray into the advanced settings.
Killer Bandwidth Control allows control over both priority and maximum bandwidth for individual programs. It's nice and easy to use, but my only complaint would be that the bandwidth options cannot be customized, so I couldn't use a 10 mbit/s bandwidth limit which I needed.
Finally, Killer Firewall blocks all communication except specific port / program combinations. I found it nice and easy to set up. Killer recommends using the firewall for security while in your routers DMZ for speed, which seems to work well.
Super Advanced Awesomeness
So far, I've been treating the Killer NIC like a normal network card, but under the hood it's an entirely different beast...
The NIC is actually a PowerPC processor running Linux, which allows you to do some amazing things.
Firstly, by bypassing the networking stack and using the processor on your NIC, you free up your CPU to do other things, like run games as fast as possible.
Second, the firewall and bandwidth control applications are running on the card, so there's no appreciable performance hit to using them.
Third, and probably best, you can run any compatible software you want on your network card. My personal favourite would have to be FNATorrent - by plugging in an external HDD to the USB connector on the back panel of the card you can download torrents (think WoW patches, creative commons music, open source software...) without ever using your main CPU or memory. This NIC is all about taking the strain off your other components, and once you've moved your firewall and torrent client to your network card you've got a serious edge in a competitive environment like online gaming.
A full development kit is even included on the software CD, so you can write your own programs to run on the Killer.
Conclusion and Overall Impression
Hardware-wise, this thing is a monster. There's nothing like having a 400MHz computer inside your computer to really get some geek points.
While the included software isn't perfect, it's pretty close and I'm hopeful that future versions will iron out any minor problems.
My experience with the Killer NIC has been very, very positive. Gaining better control over your network traffic, pings that are often bordering on unfair and lowering the strain on your system has no downside. I'm certain that I haven't seen half the amazing thing that this card can do.
This certainly isn't a network card for your average PC user, but if you've just spent $250 on a NIC (or won one in a competition!), you're probably not an average user anyway. With a little time, effort and a willingness to just play with the Killer, you'll be richly rewarded.
So in conclusion, if you've just spent a big 'ol pile of money on a serious rig, why use the same network card as the novice user next door? Splash out on one of these - you won't regret it.
