Overclocking is tuning up the speed of a component to squeeze a few more megahertz out of your component until it mega hurtz(see the pun?).

First, my CPU costed around US$350! For a similar performance, the Intel Pentium G3258 is a third of that cost AND fits in with other components exactly the same.

Before the G3258, the only overclockable Intel processors were way up in the i7 and i5 price range. As casual gamers, or performance enthusiasts, it is very difficult to reach those high prices and now, behold the G3258, a chip that overclocks and is in a friendlier price range.

More about  RAM

For RAM, just go to any computer store and get a dual-channel DDR3 RAM kit of a capacity of your choice, make sure the brand is reliable. Kingston value RAM is a good choice for casual users. Remember that for most PCs 8 GB will do.

Now, about speeds, the difference is too small, it doesn’t matter. Even the difference between the same capacity of DDR3 compared to DDR4 is very little. The only time you should be buying more expensive RAM is,  when you are looking for aesthetics.

Avexir core series might be a good choice for aesthetics. My recommendation is just one piece of 8 GB Kingston value RAM. Now, there are memory kits that include more than one piece of memory. You can learn about memory kits here.

More about motherboard

For your motherboard, things to check:

  • Compatibility with your CPU,  i.e. make sure your CPU has the same socket type as your motherboard.
  • RAM compatibility, ie  make sure the motherboard supports the speed of your RAM.
  • Lastly, if you are planning to overclock your CPU, make sure your motherboard has a “Z” or “X” in front of it. Others will not have this feature. My recommendation is the msi Z87 GD65. It has support for SLI and Crossfire and has some pretty great aesthetics.


More about Graphics card

This component is the most important part of a gaming computer and for anyone who wants to have a pleasant computing/gaming experience, buy a good card. Instead of looking for the latest budget card, search for a chart of the performance of many graphics cards on your target game or program. We are looking for the performance over cost value. In other words, the best performance per dollar. I recommend none other than R7 260X. This card is so similar in performance to the GTX 750ti and is cheaper by a landslide. If you are into it, buy a GTX 960. A little bit more invested here, will last a few more months or years before a necessary upgrade.

More about PSU

For the PSU, check this  power calculator for finding your needs. I suggest something from the cooler master elite series for casual users though you can go with anything that has more wattage than your PC needs. Make sure that your PSU has the necessary connectors for your motherboard.

  • 24pin for your motherboard
  • 4 or 8pin that plugs in near the CPU
  • SATA connectors for your optical drive(s) and storage drive(s)
  • and last but not least, some graphics cards need 6 or 8 pin connectors for additional power

A cooler master elite 460watt PSU is good for most PCs.


More about coolers

Coolers, the rich kids got their fancy sub-zero coolers and a million RPMs in super quiet mode. But if you aren’t any rich, fancy kinda guy, be happy to hear that the cooler that comes in your CPU’s box does a good job already and also supports a very mild overclock before it gets too hot. Next time you have some money saved up, you can get yourself a cool liquid cooler though I don’t recommend it as it may not be really worth the cost.

If you do have the chance to get a liquid cooler, I recommend one from the Cooler Master Seidon series as they are quite cheap compared to other brands and still have the performance needed for overclocking. Before buying a cooler, check that your case has the space required for mounting the radiator. For this CPU, a 140mm or 120mm single radiator is perfectly fine. Bigger ones give better temps but are not required. Don’t forget about case fans. There is usually a fan provided with the case but usually more are needed. Adjust the fans to guide the air through the case. Have an intake and exhaust.
