Cheaper running costs?

[OldChap]

This question is for those of you who moved here from Folding....

Do you find any reduction in running costs on Grid?

I noticed the card running at lower temps and automatically thought the load must be less which made me wonder if this translates to a reduction in costs?

I did some measurements (http://spreadsheets.google.com/pub?key=rYPquhU1dvJZqYsekcZvqfw&output=html) some time back and got a 37 watt difference between GPUGrid and F@H on dual GTX 260.
