Hi Anna, I think you were asking Crusoe this question, but I'm not sure that he checks in here too often so I will give you a quick answer.

> What is Parallel desktop?

Parallels Desktop (http://www.parallels.com/en/products/workstation/mac/) is a program that lets your Mac run Windows programs directly. There have been other mechanisms to do this in the past, but Parallels uses a newer method that runs much more transparently and faster than previous mechanisms.

However, the one area that can still tend to be a problem is 3D graphics support, I'm not sure how well Parallels handles this, possibly not too well.

If that's the case, then there is another option for you to run Windows software on your intel imac, called "Boot camp" (http://www.apple.com/macosx/bootcamp/). This allows you to just run Windows directly on your Intel Mac hardware, not using any kind of emulation layer at all. So that will definitely work fine.
