I currently upgraded my cpu, ssd, psu, and will upgrade my gpu:
So this will be the system I will use. I have never overclocked or even really know what it is. I know you can over clock your cpu or gpu. So I would like for someone to please explain what is it, why you should over clock, how you over clock, and if my system can even over clock and would it be worth it.

MOBO- Gigabyte GA-78LMT-USB3
RAM- 8gb
CPU- AMD FX-8320E Eight-Core Vishera Processor 3.2GHz Socket AM3+
GPU- AMD RX 480 (when released)
SSD- SanDisk Ultra II 2.5" 240GB SATA III Internal Solid State Drive (SSD) SDSSDHII-240G-G2
HDD- Toshiba
PSU- Thermaltake PS-TPD-0850MPCGUS-1 850W ATX12V / EPS12V 80 PLUS GOLD Certified Active PFC Modular Power Supply

Overclocking is what it says. CPU and GPU comes with "stock" clock speeds, overclocking means putting higher clocks than "stock" clocks. Of course, higher clock speeds mean more processing power. Motherboard has very basic VRM so I do not recommend overclocking and so I don not tell any instructions. For GPU, not much to say as it's not released yet.

I've never overclocked, so I'm guessing here.  If overclocking also means computer runs from Warmer-to-Hotter, and heat is an enemy of desktops/laptops, then extra cooling may become mandatory.  For desktop: consider adding a room fan to better circulate air, extra fan inside the desktop.  For laptop: consider a usb external cooling assembly [one giant fan or twin fans].

What is overclocking, OCing is getting the most out your system performance wise (best bang for the buck). Optimization is key and is never achieved by using default Bios settings.

Almost all quality components will see gains in performance, some only show in benchmarks but others you'll actually "feel" the change/increase (thinking gaming or video encoding here).

Once you've experienced these gains you'll never want to go back. I've been feeding the addiction 24/7 for seven years now.

 

As mentioned above any time you add performance to anything you'll be adding heat into picture.

You'll need to upgrade the cooling solution and make sure the current case has very good air flow.

 

The 8320e is a nice chip and should OC nicely on a quality mobo but...

Your current mobo has only a 4+1 VRM Phase Count (voltage regulation) I would not recommend anything less than a 6+2 Phase Count to OC an FX8xxx. Most of us run 8+2.

It's also a Micro ATX which is also not something you'd OC on. I would leave settings at stock if it were me and look to upgrade the mobo before risking any damage due to over heating VRMs.

 

Here is a very good place to start if you have the interest in learning to OCing that 8320 http://www.overclock.net/t/1348623/amd-bulldozer-and-piledriver-overclocking-guide-asus-motherboard

Feel free to PM me if I can any further.

Overclocking is exactly what it says, increasing the clock speeds of the CPU, GPU, memory bus, etc so they run faster. The process involves increasing the clock speeds and changing combinations of the clock multipliers (there isn't just a single "clock speed" to change, the multipliers also have to be changed). Along with these changes, it is also common to have to increase the voltage, which in turn creates more heat, which leads to a need for better cooling. "Extreme" overclockers usually end up with expensive liquid cooling set ups to deal with the excess heat.

How much performance gain do you get? It depends on the chip(s) being overclocked and how much of an overclock you can get. Identical model CPU's, for example, will not overclock the same. One will typically will go higher than the other and so on. It's really a luck of the draw in your CPU, although some models in general are better for overlocking. Also, you have to be sure your CPU is not a "locked" model (meaning it isn't overclockable).

Actual performance gains can be decent with the right CPU, but on average it's a few percent increase, up to maybe 10-15% on the high end. The question is, is it worth it? If you're a hardcore gamer looking for every last extra frame you can get, then maybe. For day to day stuff, not so much.

One thing to keep in mind, overclocking stresses the components and if you aren't careful you can easily fry a CPU, GPU or other parts. Just like bumping the HP up on your car engine, you can get more performance, but the cost is a shortened life span, usually. More stress on the components.

My personal opinion is that overclocking isn't necessary in this day and age and not worth the extra cost or potential headaches, but it's a way to learn more about your system, so go for it if you really want to.
