3-D. Is it worth it?

The cyan/red-combination is in my opinion a joke...you can't compare that to the Edimensional glasses - they do something completely different. BTW: Hopefully you already have taken a look at edimensional homepage for further info...The cyan/red stuff gives you 3D by dividing the image in red/cyan so don't expect to see the original game's colors then (though you also don't see only cyan/red...it's a mix of these colors). I think for the performance question, the best way is to ask edimensional itself - the support is very good and you'll likely get a fast reply.Stefan
