How true. History keeps repeating itself. Compared to their bread n butter cards both companies work less on drivers and performance to clear up dual GPU issues because it pales in comparison in sheer numbers to single GPU owners.
The 580/560 or the 6970/6950 cards outweigh importance over dual GPU owners and focus is on the majority not the minority. It's always been the case that dual GPU owners have less performance boosts and driver improvements than single GPU owners with two single cards.
Unless your restricted to one PCIe slot, can't afford two or don't want to sandwich two together in SLI/Crossfire without space in between then there is no reason to buy dual when you'll get better performance with two of their single counter parts.
As for the OP
, at this point you'll need to upgrade to a 120Hz monitor, buy some Nvidia 3D glasses and your money won't be wasted on a single 60hz monitor where you not going to get close to full potential due to your limiting factors.
I just went 3D with just one GTX 580 and it's awesome fun, it's like your inside the game yourself. Pretty submersive not to mention 3D movies are cool to watch every now and again.
If not a 120hz monitor get a second 60Hz at least and enjoy wide screen 2D gaming.
Everyone likes over kill here but it's got to at least produce higher end results or your just throwing away your money without anything to show for it.
