PCI 2.0 Card in a PCI 16X slot

I feel like I know the answer to this..... but im just checking to be sure.
If I put a PCI 2.0 2x Sata III card in a PC16x in my PC am I going to get the full 6 Gb/s out of the sata (or as at least as fast as a real PCI 2.0 slot)?

My mother board is

And an example of the card is

  1. Nope. It's a 1x card, so 500MBps (or is it Mbps?) is all you can get. 500MBps isn't to bad, you'll get most of what a SATA 6.0 ssd can do. 500Mbps is a lot worse. You also probably can't use it for a boot drive as much motherboards won't boot from a PCIe slot. It should be great for any optical drives or spinning data drives.
  2. So even though its advertised as a sata III card and that it will do 6 Gb/s....
    What if I did a 4x card?
    Im less worried about what the card can do and more worried about the throughput between the motherboard and the card. My mobo is older and im trying to get sata III and/or usb 3 running at top speed if possible. All I have available to me is a 16x slot and a PCI express 1x 1.0 slot, and im trying to figure out the best setup to get the most speed (cue Jeremy Clarkson)

    They advertise slow spinning hdds at 6.0 as well. Even though most can do 150MBps tops. But they support the standard, so they say "up to" and call it a day. A 4x card would support the full speed, but not a 1x card.

    That's exactly what I'm talking about.
