Query: First one was DOA but second one works great.

I had to remove a star because the first one was bad. Wouldn't let my computer boot up.Amazon replaced it quickly and the second one works fine.I needed gigabit to speed up transfer of movies to my htpc hard drives. I have an htpc with 2 usb 3.0 seagates full of movies. Transferring movie files from my desktop to the htpc took a long time with 10/100 Lan. I couldn't get on the internet while transferring movies because my network card was maxxed out.After installing this card my transfer rate went from 10MB/sec to 80MB/sec. So I can now transfer movies to the htpc or any other computer on my network plus surf the net without any problems.Note that you will only see 30MB/sec if you are using usb 2.0 drives but that has nothing to do with the card.Didn't need any special drivers with Windows 7x64. Worked straight up.
