No!!!!!

Not true. Nothing to do with the scaling in pruority. It could only be a cheap upgrade, if the game you are running is already performing well or at least have all feature supported or the game makes no problem on gpu clock speed and vram usage.
Otherwise using sli has not the wished effect.
And when you think, that in general sli only uses 50% or 70% from the second gpu in average, the costs are not that low. Add the power consumption and the problems, you usually have and a new single card will be the better upgrade.
Sli is a method for enthusiasts or for people with very high resolutions due to triple monitor, for example. To upgrade an insufficient card with an additional insufficient card is not a very genius idea. Sorry, but I always recommend buying a sufficient new card, preferrably a single gpu.
Let us see, what future techniques can change on that. I personally think, that no business related company would grant you a sufficient upgrade with a phased out and cheap card, where tjey do not earn money on! Think about that. Ati and nvidia have no priority to give you such an opportunity. They would like to make money and as long as games are also working closely together with them, they will also do not have this as priority. They recommend some support from the card producer and the give support on sales of new products.
I am going so far to say, that game devs know, how to program a game bad enough to let you buy a new card.
