Summary: smokin' fast. was having speed problems with the onboard NIC on a new/fresh system. only posting 100Mbs in both windows and ubuntu. wasn't about to tear it back down to warranty the motherboard. intel to the rescue. 1000Mbs speed now.
Summary: While gaming I was disconnected a lot using the Realtek network chip on my P6T Deluxe motherboard. This solved the problem, my connection is much more solid(I use cable connection for internet), and I can game with less disconnects and more processing power for gaming.
Summary: Its an Intel nic. It just simply works without any issues. Side not, its compatible with certain linux/bsd distros that let you combine multiple nics (ie: this one with the onboard one on my motherboard) for greater throughput which helps if you're using this in a PC that's going to serve as a NAS.
Pros: It simply just works, plug and play, no hassle. Worked in Windows 7/8/8.1 and now 10, worked in Linux (debian, ubuntu, arch) and it worked with FreeNAS as well. I get full gigabit speeds and never lost a connection or anything like that. The good thing about intel is that it has a lifetime warran...
Cons: No flashy utilities or shiny user configurable QoS setting utility for windows or anything like that. Some other manufacturers include those utilities so you can give priorities to certain programs (like Games or streaming videos) so those programs dont get bogged down if you're running torrents ...
Summary: Currently most devices are connected via Cat7 ethernet. Since upgrading the network online gaming has been considerably responsive. To compliment that I disabled "Interrupt Moderation" (set to none) and used a few registry quirks.
Pros: Connects to the internet Small form factor Nice configuration options
Cons: Drivers from the website did not seem to want to install yet using windows automatic driver install it seemed fine (which were equivalent to the same drivers I tried using manually)
Summary: Snap it in, plug in your LAN Cable, and you're good to go -- with connection speeds of 1 GB/s. It's a must-have to get maximum connection speeds with the new DOCSIS 3.0 Cable Modems. I've had 2 of these installed for several years, and they work perfectly.
