It is hard to recommend which card to take since we didn't test both of them. It might be that internally this works as a SLI card. For some reason SLI is not really fast in Lumion which we will have to take a closer look at.
The processor speed of the 590 is lower then the 580 so with bad luck the 590 is slower then the 580. If you want to be sure you get a great card get a high memory 580.
Probably these cards are both really fast but before someone takes the chance and tries them out we won't know 100% sure which card is best.
