personally I hate dealing with dual cards. There are heat issues if you don't have enough airflow. I always try to stick with a single card if I can. Right now, at least in the US, there are alot of great deal on GTX470's. I think for the money this is the card I would get. I don't think I would move to the GTX480 since the GTX570 will be coming out around December 8th and will basically get the GF110 version of the GTX480. It is expected to retail for $350-$399 USD.
