Seriously, if you have a decent psu, even a 500w 80+ bronze you can run them, and even oc them

But an intel chip at 65w that can do the same amount of work of an amd that needs 125w, well that's half the power usage means half the electrical bill and half the heat created, thus warming a room that might need to be cooled with more air conditioning, and costing more power. My 8320 oc'd and video card going full out doing something, I can tell walking into my room if my PC has been on full or not just by the temp. lol.

That only applies if they are un-overclocked. Once overclocked you are outside of the Thermal Design Power.

A quick comparison of the FX-9XXX series and their 200W TDP tells you what you have to do to get the AMD chips to run flat out. Intel is similar, the very high speeds are reached at draws as much as 160W (more for the big CPUs on LGA2011) when the TDP of Haswell is 84W, and Ivy bridge is 77W.

Not a huge factor to the enthusiast except that in general high-end overclocking AMD boards need a little more oomph to reach high clocks, but since Intel limits overclocking to only the performance boards, it is sort of a wash in terms of costs.

For the enterprise, Intel chips save on electricity in the long run (better battery life on laptops too)

Well I want to get a FX 8320 and I keep my PC near a hot radiator and I get about 23C with my actual Core 2 duo e8400 and the 212 evo...

The FX-8320 won't be unbearably hot with a 212 EVO, probably about 40odd degrees maybe 50.

Nothing too bad.
