We have some dated (over 4 year old) desktops, and have done some upgrades to them over time (new video cards, new hard drives, new DVD burners, and after the rest of the house went gigabit we wanted new network cards as our old PC's only supported fast ethernet).
This Intel card is not only fast, but offloads a bunch of stuff to the card, helping to improve overall PC performance. We purchased a bunch from another site, and after about a year, one failed. After deciding to replace it, the price winner for a single unit was Amazon.
If you need gigabit speed, and have an older PC, this may help a bit. It seemed to lower our overall CPU consumption and network responsiveness seemed slightly improved. Though we have no real way to accurately measure what changes occurred with respect to network performance as a result of installing this card.
The jumbo frame support seems to be inconsistent between various vendors, after a lot of experimentation, it seemed better to disable rather than enable it. Traffic on our LAN and across internet grows every year. With these cards, we'll be set until we need the next generation of PC.Get more detail about Intel PWLA8391GTBLK PRO/1000 GT Desktop Network Adapter.
