Summering: The headline says it all. Windows XP gave constant error messages. Windows 7 had delays in all phases of networking but no error messages. Replaced it with an older card from an obsolete PC and now have a fast connection.
Summering: I first learned about this product via specialist internet forums where it was always mentioned as the gold standard in single gigabit ethernet cards. Even with all the hype, it is all that I was expecting and then some! Thanks to this device, I'm now able to download from Steam at 19MB/S and my gaming pings are usually around 4ms.
Summering: I bought this card as it was made by Intel and was in the right price range for me. My old on board network card (Broadcom) had given me nothing but problems. This card arrived promptly, was easily installed and works flawlessly. Highly recommend it.
Summering: ESXi is picky when it comes to network cards, so even though my new motherboard has a network card on it, it was necessary to get this for compatibility and virtualization. It does the job well and there's not much more you can say about a network card.
Summering: Wollte die CPU - Last senken, da die interne OnBoard Netzwerkkarte fast immer 90% CPU-Last brachte. Nun ist diese verbaut und alle Treiber installiert, und nur noch eine Last von 10% CPU. Und auch sehr stabil.
