GPUs don't follow Moore's law.
Yes they do. Transistor density in GPU (and thus hashing power) has doubled roughly every 24 months. If anything GPU development more perfectly follow Moore's law.
Do you mean potential hashing power? Because transistor count and hashing power are not directly correlated, as noted by the 2billion transistors of RV870 monstrously crushing fermis 3billion transistors in hashing power.
+1 Moore's law doesn't really apply to GPUs because for their different architecture nature than CPUs, Moore is more into RISC and CISC architectures.
I have found this chart interesting.
difficulty by itself really has no meaning for a miner.
USD:BTC by itself likewise really has no meaning.
What matter is price & difficulty.
If price of BTC falls 90% and difficulty falls 90% I will make the same amount (in USD).
Likewise if price of BTC rises 500% and difficulty rises 500% I will still make the same amount (in USD).
Till now I haven't seen a good way to express that important relationship.

This chart illustrates it well (showing daily revenue in dollars per 100MHash/s).

Long term we would expect this trend to fall continually because the cost to produce 100MHash/s rig continually falls (faster and cheaper GPU due to Moore's law).
Great chart by the author (although I think changing the unit to GH/s might be more applicable today).

FYI, this is what it says on the PSU:
http://www.xbitlabs.com/images/coolers/1000w-psu-roundup-2/9p7s.jpg
Thats "only" 1320W on 12V lines, which is all that GPU's use.
Even at stock speeds (edit) 300Wx3 + 375W = 1275W for the GPU's alone. Granted, thats TDP, while mining at low memory speeds it might be lower than that, but you have other devices that need 12V, not in the least the CPU.

+1, u need more power
Re: I Manufacture machines that generate free electricity. A match made in heaven?
Re: Dont buy overpriced PCI-E raisers / extenders weight your options!
i got 2 PCI-PCI-e converters from ebay, i had issues with win7 enabling the device within my mining rig (asrock X58 extreme with 4 6950 and 1 5670 getting 1.6 GH/s),
however on boot the converter worked fine on a second mobo with the 4870 plugged into it, i still need to do more investigation, but i don't want to disturb my miners!
