Well with temps that high you are going to get some fruity esters in your final product. this isn't necessarily a bad thing, but it depends on what you are trying to make. For instance, a heff, wit, or even some pale ales can do right with a little bit of a fruity finish, but something like a Kolsh would be better off without.
My advise would be if you are stuck with fermentation temperatures that high, stick with styles that will benefit from a warmer ferment, otherwise look into a son of a fermentation chiller, or search fermentation chiller or fermentation cabinet, or get a refrigerator and temperature controller to help keep you beers fermenting at an optimal temperature for your style
