Tip: I would alway use target="_blank" to open a link inside a new window.
The target "_new" is no reserved name in HTML which means it's a "normal" window name.
The problem that might occure with that (which might confuse a user): if the user does not close the window which was opened with "_new" and sends it into the background instead all further links he clicks on with that target will change the content of the window in the background but the user might not see it. For him nothing happens. _blank makes sure that always a new window is opened.
