ATI HD3870 = 106W x2 = 212W (@496GFLOPs ea. = 4.68Gflops/W)
HDD = 20W x3 = 60W

1 stick RAM = 10W x 6? = 60W
80mm fan = 2W x3 = 6W
120mm fan = 2W x3 = 6W
TOTAL for 3 rigs: 714W x 1.2 (for Min. inefficiency of PSU) = 857W pulled from wall.
Total processing power (CPU + GPU) = 66.5 + 992 = 1058.5 GFLOPs
Your current combined Efficiency: 1.24GFLOPs /Watt

TOTAL for new rig: 362W x 1.2 = 434W pulled from wall.
Total processing power (CPU + GPU) = 83.3 + 2720 = 2803.3 GFLOPs
Your NEW combined Efficiency: 6.46GFLOPs /Watt

I think that might be enough to convince her - new rig is 5.2 x MORE efficient than running the 3 old rigs put together. In other words, it has 2.6x the processing power, and uses exactly half of the electricity to do it.
Hope that helps!

I think you are confusing CPU TDP (Thermal Design Power) with electrical power consumption. TDP refers to the max. amount of heat in Watts a CPU is designed to generate. All current CPUs use a lot more electrical power then their TDP rating.

Take a look at this ---> http://www.tomshardware.com/reviews/...5,2278-11.html
TDPs, GFLOPs per Watt, efficiency ratings. ROFLMAO How long have you guys been married???

Slicker... I'd go for the Rose Oil. Sure, it's $200 a half once but I think it will go further with your wife than GFLOPS per watt. Just my opinion.
