Agreed.

Actually, the 2900XT pulls about 90w more only against the 8800GTS 320.  Comparing it to an 8800GTS 640 this narrows to 65w and finally drops to only 17w against an 8800GTX.

You do not need to have an 8-pin connector in order to use the 2900XT.  The only time you need an 8-pin connector is if you intend to overclock the card and void your warranty.  The 2900XT works just fine with the 6-pin connectors.

The GTS consistantly outperforms the 2900XT from what I have seen.  Granted, they are usually pretty close and the 2900XT wins a few tests, but really the 8800 is the superior card.
		
		
	 
I thought that the newer drivers put the 2900XT performance above the 8800GTS 640 and within reach of the 8800GTX.  Or did Nvidia also have some major driver improvements which placed the 2900XT back to 8800GTS levels?

I do agree that you will save money, but it is a very, VERY, 
VERY small amount.  Even if you compare the 2900XT to the 8800GTS 320, that's a 90 watt difference.   The average time spent playing games is 
8 hours per week.  8 hours per week x 4 weeks per month x 90 watts = 2800 watts = 2.8 kW x .05 cents per kW = 14.4 cents per month.   That amount is so negligible that it cannot even be considered a relevant factor.

Since both cards have DHES coolers that vent their hot air to the outside of the case, I don't think either one will raise case temps.  In fact, they might even help lower temps on a poorly ventilated case.
