Support for motherbord

you just need to go to the website of your motherboard brand, then after that you just click the motherboard, when you are now in the site just type your motherboard model, then click the driver, then chose the US when you download the sound and video driver

It really depends on how much money you wish to spend and with that comes the features you can enjoy. On the lower end you will end up with mATX motherboards with on board video and not much expansion/slots, in the middle of the pack $80-$110 more slots are available and possibly SLi/Crossfire capabilities. The higher end boards allow you to have the features of the other classes, plus more memory, slots, fancy heat distribution equipment, and exotic chipsets. I prefer Gigabyte, Asus for the higher end and medium to low I tend to look at MSI, Biostar, DFI, Abit.

I hope this helps.

Yes, every processor can be overclocked, but be very careful when overclocking processors. The increased heat can damage a processor and shorten it's life significantly. Ensure your processor does not get too hot during the oveclocking procedure. All overclocking should be done in small increments. The X3 8600 can be oveclocked to close to 2.7GHz safely with air cooling.
The best overclock is always through the motherboard. Depending on your BIOS you can raise the Front Side Bus (in small increments) in order to bump up the total frequency. If you have an unclocked processor, you can try to raise the multiplier. After every increase, you should stress test your computer using PRIME 95. If your computer locks up, drop down the clock speed and leave it there. Your computer should always be stable. You may have to raise the voltage of your processor to get to where you want. If you give the model of your motherboard, I can give you more detailed instructions.
Make sure you have CPU-Z (http://www.cpuid.com/softwares/cpu-z.html). - this will show you all the details of your processor. If you would like some more detail, check out this link:http://www.wikihow.com/Overclock-a-PC and feel free to message me. If you didn't understand some of the things in this post, I'd recommend not overclocking your PC - it can be dangerous and ruin your computer if you don't know what you are doing. Alex
