would it be a daft move to go from xfire to sli with the cards in question ?
Do you have a link showing newer drivers used on a sli 470 setup and better breakdown of the scaling?
Crossfire provided with an average frame per second improvement of 62%...
Then we have the GeForce GTX 480 SLI cards which cost ~25% more than the Radeon HD 5870 Crossfire graphics cards. However these cards were able to scale considerably better providing an average of 90% more performance
Thanks for the link, shame again that there is no breakdown of the scaling
