Can my PC operate a SATA II card at 3Gb/s speed or only 1.5Gb/s?

I am purchasing a PROMISE FastTrak TX2300 PCI SATA II 2-Port 3Gb/s RAID Adapter for my Dell Dimension 8300 PC and will be using it with a couple of Seagate Barracuda SATA 3.0Gb/s hard drives. Will my Dell Dimension 8300 be able to operate the drives at the 3.0Gb/s speed, or will it only run at 1.5Gb/s. The disks come with a jumper on them set at the 1.5Gb/s speed by default. You can take the jumper off and run them at 3Gb/s if your motherboard can handle that, but I don't know if it can.

Yes, the Dim 8300 uses SATAII so that means 3.0GB/s. Make sure to remove the jumper from the Barracuda drives before you install them. I use Barracuda drives too and forgot to take mine off at first and it does affect the performance.
