You will not see benefit from SLI in Lumion. The developers suggest the largest single core card you can afford. That said, it appears the card is a single core and has memory to back it up. It is on par with the GTX 680 single core, with the 680 edging the AMD card slightly on some tests. Please note, the developers have said that GTX cards seem to run Lumion better. I would think this would work for you as long as you have the card slots and power supply to power either card.
Good luck in your choice.
