    I wanted to get a new hard drive with the 6 gb/s speed, but i've read it's not really a difference. I wanted some opinions

    If its a mechanical disk, don't worry about it; they won't be fast enough to utilize that kind of thruput.
    If its a SSDrive, some of the cutting edge ones are getting up to that 3 gigabit per second limit. Right now 6 gb/s controllers are more of a future-proofing because SSDs are still getting faster.

    So a 6Gb/s SATA controller with a 6Gb/s hard drive attached will perform exactly the same as a 3Gb/s controller and drive?

    Mech hard drives are limited to approx 100mps transfer speed. No matter what controller you use, you are not going to see any more performance. The only thing that comes even close to the theoretical speed limit is a ssd drive. As they improve, you may see a use for the new sata3 controllers. My current ssd drive has a max speed of 285mps or so.
