While it is true that, percentage wise, more people can view 1024 px without problems, almost as many still use 800px so you might find that a lot of people who do not like the horizontal scroll will move on.

Consider placing the back bottom near the NAvBar, that way users will not use their browser's back button.

Also, if you use a smaller text (NavBar) the titles will not be cut off.

good luck
