The only thing that is a bit puzzling is what will happen to Tri SLI as the 8800 GT and the new G92 based 8800 GTS 512MB don't support this technology.
Some vendors already stopped orders of these cards but the new G92 based 8800GTS 512MB won’t have two SLI connectors and won’t fit in new Tri SLI concept. This is rather inconvenient for Nvidia and the delay of 780i motherboards made this product rather obsolete even before it launches.
It won’t do much good if you buy Tri SLI and weeks after Nvidia reintroduce D8E based dual cards with dual chip Quad SLI, the concept that might be even faster, potentially even cheaper.
One thing is certain, G80 based cards are receiving the "End of life" tag and in January Nvidia plans out to execute End of Life for 8800 Ultra, GTX, GTS640 and 320 cards. You served us well, you may rest in peace now.
