No, I don’t think its worth the money. Instead of buying two good cards, buy one super-good card for the same price, which will serve u just as well (if not better, since the benefit of a second card is somewhere close to 50%, and the power requirements are huge, etc…), then in the future you can upgrade and get a second card as SLi or for PhysX if you’re using nVidia, although right now ATi has the best bang for the buck since the GTX 400-series is quite a dissapointment
