Home / Business / Ultimate differences?

[StarSolitude]

Hi, I'm building a new PC soon, and I'm buying a new Operating System to go with it. I'm using Windows XP, which is an "upgrade" version right now.

Ultimate is very expensive, and I don't want to be paying for features I don't need. Gaming is my passion, so it needs to be 64bit. I'm not interested in networking or using my computer for "business/work."

What are the main differences between the Home / Business and Ultimate versions of Windows 7?

Thanks. It seems that Home Premium will be fine for gaming.

Edit: Just one more question... Why is Windows 7 Home Premium about the same price as XP Home Premium? Surely it should be more expensive... Something seems odd about that, wheres the catch?

Why should it be more expensive?

Erm, newer / better things are usually more expensive on their release than years old things...

So, after pre-orders it will be more expensive?
