How fast can a PC run OSX?

I'm planning on buying a new laptop very soon. I was originally considering a Macbook Pro because I'd be using it purely for design, photography, and art needs. Seeing as OSX runs Adobe software the best, it was my top choice.

Now, seeing as PC laptops are a lot cheaper for similar specs, I'm now planning on buying a PC and installing OSX on it. However, my question is, how fast will a PC run OSX? Is it slower, equally, or faster than if it was on an actual Apple computer?

OSX will only run on certain pc's. (they require Intel processors I believe)
I'd do some research before ruling out a macbook.

So most can be run on AMD and Intel? Either way I'd be getting an Intel processor considering they are a lot better than they used to be.
