No :( Can't find a Nvidia driver that's stable enough to support it. Haven't found any solutions online besides going back to a 260.1 driver which only gives around 30 minutes of gameplay before freezing. Apparently the ATI Eyefinity works a treat with 3 screens though, but own't be trading these GTX 580s for anything. Might just have to wait until BF3 for some 3 screen BF goodness..
