I refuse to run Windows and there are many streaming video apps (especially Silverlight and some Flash) that won't work on Linux. Vimeo is one example.
Power goes up linearly with frequency and with the square of the voltage. You do the math.
My overclocked FX8150 heats up my office nicely (by at least 10C) if I run Prime overnight.
I bought the 4GB Elpida C DIMMs from Directron. They're low voltage RAM, 1.35V nominally (but OK for 1.5V), and I overvolted them to 1.45 and run them at 1866 CL10. Works nicely.
Yeah they have a temperature sensor on the module but the Linux kernel still doesn't have a driver for it :(

Th 4GB Kingston DIMMs I run are rated at 1.35V nominal to 1.5V. Check the data sheet for the DIMMs. It's quite probable that they'll run at up to 1.5V.
I run ECC RAM on a Crosshair V with FX-8150. Kingston low voltage 1333 overclocked to 1866 at 1.45V.
All Bulldozer CPUs support ECC but the BIOS has to turn it on.
It's working for me but I'm still at the overclocking stage - I only finished the build (FX-8150) a couple of days ago. So no virtualization yet. But at least ECC memory (16GB Kingston KVR1333D3E9S/4GEC) and lm-sensors work well, except for the temp sensors on the DIMMs. There is allegedly a...
