The averages are much lower, but I said "If".
"If" you are paying 40c per kwh, than the cost to run a high power GPU (or even worse, an SLI or XFire setup) vastly overshadows the cost of an FX-8350's extra power usage. This is simply a fact, not an opinion.
We are talking about the difference between a 30-50W premium for running an 8350, vs using an extra 200W or more for a high power video card compared to something efficient like a Radeon 7790.
"If" the power usage of the 8350 is too high, then the GPU's 4X higher consumption will be even higher, every single time. Your cost for electricity isn't a relevant factor, because the GPU is going to be using a greater share than the CPU for any gaming situation.

Then you shouldn't have high end video cards, period. They are simply a luxury, nobody needs them. You buy them because you want them.
