During our benchmark session, we tested all cards in non-SLI mode first, before moving to hybrid SLI. Unfortunately, the motherboard’s "power on" circuit was apparently damaged following the re-installation of the GeForce 9800GX2, and we were unable to test the chipset’s HybridPower capabilities. The non-hybridized 9800GX2 performance results were maintained for eventual energy efficiency comparison to lower-power cards.
The 8400GS gets big help from Hybrid SLI in Crysis, but it’s still unplayable. At the other end of the performance scale, the 9800GX2 is so powerful that the AMD Phenom X3 8750 is unable to keep up.
The low end cards get no relief from Hybrid SLI in Prey, losing around 1% performance with GeForce Boost enabled.

Can someone answer me the question. Why is onboard graphics so much better at preserving energy per performance amount than a normal graphics card.
You can't play most games at 100x100 on an onboard chip so there is nothing to use any energy.
You thrown in a 3d Card which has 1000000x more transistors and you have to power them up to get the game moving. I hope the next war for gfx card speed will be fps per watt. 1watt card running at 60fsp will do me.
My PC broke last year and there was a dip in my bill for the month that I didn't play games. Thats a worry for me. Soon it wont be the cost of the game; but how much I have to play to power my rig per level.
will you be recieving a new motherboard to run the tests again with the 9800GX2??
That last graph (performance per watt) is completely flawed because it doesn't take into account the energy used by the PC. Unless overall system performance per watt is what you wanted, in which case it gets a lot more complicated...
btw looking at the impact on power consumption of limiting performance via v-sync (or another mechanism) would be interesting for a future article on power usage.
