No, not really. When the new cards came the offered about twice the performance of the old cards. Instead of shelling out $400-600 for that kind of performance you shell out $200 or so to upgrade to such performance saving you that much money for when you go all out on a system again...
Except the fact that you never know how fast the next gen will be.
Say you buy a 6800GT PCI-E and a dual PCI-E mobo this fall, if its out then. Then say a year from then, you want more performance. So you think about adding another, for probably about $200-$250, new or used. Except the new $400 model is 2x as fast as the 6800GT. So you can either buy another 6800GT, and SLI it. Or you can sell your old 6800GT for around $200'ish, and put the other $200 towards a new card. Either way you get about the same speed. Would you rather have two card, sucking up more juice and producing more heat, or just one card, that might even have more features? The choice is simple for me.
Perhaps the new card wont be 2x as fast, but you never know. I would have never thought the X800/6800's would be twice as fast in newer (DX9) GPU intensive games, but they in the settings I play in.
I dont think buying into SLI with the thought of upgrading a year down the road is a good idea. Things change so fast, its probably not going to work out as planned. Especially since a 6800GT is faster than 2x6600GT's in SLI currently, and both are about $400. Doing it with the thought of adding another in a few months makes more sense to me.
