It's been a long time coming, but I finally got around to installing my GTX 760 (pre-overclocked), CPU cooler (CoolerMaster Hyper 212 Evo) and extra DDR3 RAM (bringing my total to 12GB). It's all thanks to the fine people of PCGAF who helped me figure this stuff out, so thank you guys a bunch :3
Now, the only thing left to do is overclocking my CPU. I have an i5 2500k clocked at 3.30 GHz, and I've been led to believe it's a rather easy process. Would anyone be so kind as to give me a little instruction, or lead me in the direction of a good tutorial?
I've never done any form of overclocking before, and the hardware installations I listed above were my first time doing that as well. I am still a relative novice, so take that into mind when assisting me if at all possible.
Thanks agian,

This is probably going to be information overload, but if you want to learn the finer details, follow

It's relatively simple enough if you want to cut corners though (not really a bad thing). To be honest, this is how I've done it on a number of Sandy/Ivy builds:
First off, download HWMonitor, CPUZ, and Prime 95.
1) In BIOS, set CPU multiplier to 45. Set load line calibration to high. Disable C3, C4, and C6 "C States". Increase core voltage to 1.35. Enable XMP for memory. Enable Intel Speed Stepping.
2) Boot. If successful, run Prime 95 "Small FFT" for 15 minutes.
2a) If it fails, reduce CPU multiplier, go back to step 2.
2b) If temps are too high, or if stable, reduce voltage, go back to step 2.
3) Once voltage is reduced to a level that is comfortable for temperatures, and it passes the 15 minutes on Small FFT, let it run on Small FFT for at least 12 hours to ensure stability. I do 24 hours, but it's probably overkill.
4) If it fails during that extended period, increase volts if temps are okay.
Acceptable temperatures for a 2500K is basically below 80 for an average of the four cores. If you have a single core going above 80, don't fret it too much. Mid to low 70s is great. 60s are amazing.
That will give you a great boost without too much of a strain on the CPU, or without too much work to get the highest possible overclock. A lot of people prefer the "offset" voltage, which gives a variable amount of voltage based on the CPU frequency. In theory, it's absolutely better. With enough effort, it's better and definitely stable. However, given the shelf life of most gaming PCs, I don't find that to be necessary. I've had enough issues with stability when trying to use offset that I just don't trust it. When we're talking about low (for Sandy) voltage like 1.35, I'm really not concerned about having that a constant.
To give you an idea of what these chips are capable of, my first 2500K that I bought something like 4 years ago has been at 1.46V @ 5.0GHz 24/7 since the day I booted it. I sold the system to a friend 2 years ago, and it's still at that same voltage and speed without any issues.
