ASUS EPU
Enables the Most Energy Efficient Motherboard in the World
The ASUS EPU utilizes innovative technology to digitally monitor and finetune the CPU power supply with improved VR responses in heavy or light loadings. Working together with AI Gear 3, it automatically provides power for higher performance or improves efficiency by 50% when the PC is running low intensity applications - helping you attain the best possible power efficiency and energy savings of up to 80.23% to help save the environment.

all I am saying is the P5K/EPU with a FSB of 1600 and it can take 1200 MHz RAM will be a more stable overclocker. This board will be much better for a beginner learning to overclock. It is much easier to adjust FSB speed and not have to mess with voltages(North Bridge, CPU, RAM) to crank up your cpu. The Q6600 can get a nice overclock running with stock voltage.
Example; my set up
Asus P5N-E 650i has a FSB of 1333 MHz and my processor, Intel Q9300 has a FSB of 1333 MHz. On paper it looks like it all lines up. To overclock my processor I have to increase the FSB. They are both only rated at 1333 MHz. But my motherboard becomes unstable and will crash if I go any higher than FSB 1532 MHz (I've tried everything a person can try). That takes my Q9300 from 2.5 GHz only to 2.875 GHz. That's is all the higher I can overclock with adjusting the FSB and voltages! Not a good overclocking set up at all
Example; your set up
Asus P5K/EPU has a FSB of 1600 MHz and your processor has a FSB of 1066 MHz. On paper it looks like it doesn't match, but it does. You will be able to reach 1600 FSB easy with that board. That will in turn increase your processor speed, you will have almost 500 MHz room to increase your processor speed. It might become a little unstable the higher you go because your processor will need more power, you might have to adjust the voltage just a notch or two and you will be running 3.0 - 3.2 GHz easy with that setup.
-----this is the best way to start off learning how to overclock-----
Did any of this make sense? I tried my best to explain it, I'm not very good at writing what I want to say
Did you make a decision about the graphics card and CPU cooler? That is just my idea for you, go with a little lower graphics card (you are not a serious gamer) and put the money into a good CPU cooler because you want to overclock.
All I was saying about Newegg reviews is not to judge a product by the reviews on there, I read them and many more before I purchase a product.
I would not put extra money into a motherboard because it has WiFi, just plug your internet cable into the back and save $50 on a motherboard. That's me anyway, I live in Germany and have DSL 16,000 with a gigabyte connection so my internet is the fastest I have ever seen, for me WiFi on a desktop does not make sense. I guese it is good for somebody out there.
Like I said before...This is a place to learn and we are here to help you, we all had to learn sometime
