Only one ring on it, other is near identical. Can't just straight up stack Attack Speed, you need Crit and Crit Damage. Attack Speed will only get you so far and unless you're making a lot of use of the extra speed you are just inflating your DPS figure for the sake of it. Don't sacrifice Int to get Attack Speed.
Check out
this post on the official forums. It has a spreadsheet linked that is a calculator for a Wizard. You can enter your stats and then check the Auction House for stuff. Just put your current item in the item comparison part and put the new one in and it'll tell you how much DPS you're gaining.
Yeah mine only have movement speed and 50 Int. If I could get some with crit they'd be better for sure.
