Desktop Computer Facts

Myths and Facts about Computers

We all agree that there is a ton of misinformation out there on the Internet. We are being bombarded with all kind of information and in the end, we don’t even know what is true anymore.

It is something that applies to every niche, to every subject of interest. It is really easy to get lost or misinformed on a certain subject. Computers are no exception. There will always be misconceptions and myths surrounding computers and in this post, I am going to explain why many things we think about computers are actually wrong.

Below, I’m going to analyze 8 desktop computer facts, which many people get wrong or think that they know, but the reality is pretty different. I have spent enough time researching and building computers and that is why I can verify that the facts below are actually true.


1.       RAM does not make your computer faster

Many times people think that by upgrading  RAM their computer will be faster. Random Access Memory exists in order to transfer the CPUs workload to the RAM, which stores the data for a short time before it is being stored in the Hard Drive. When you install more RAM on your desktop computer, you actually increase the capacity of simultaneous workloads your computer can do at the same time. For example, when you have 4 Gb of RAM you can only do x amount of work on your computer. When upgrading to 8 Gb of RAM you can perform more tasks with your Pc at the same time, for example, you can play a game and surf the net simultaneously.

RAM does not make your computer faster. Even when choosing high-speed DDR4 Ram (3000+Mhz) the gains in performance will be very small compared to the amount of money you will spend to buy it.

2. If you want to increase your computer’s speed, focus on storage, Cpu, and Gpu

If you want to bring an old computer back to life, which has gotten really slow over the years, you should buy a Solid State Drive (SSD). The main reason why your Pc needs 1 or more minutes to boot into windows is that your old and rusty Hard Drive is probably dying. Hard drives are really slow compared to Solid State Drives and have very slow writing and reading performances. An SSD is almost 5 times faster and you will not believe how quick your desktop will be after installing it into your system.

If you are a content creator or do CPU demanding workloads and your Pc does not seem to do the trick anymore, maybe it is time for you to change your processor. The Cpu is responsible for every task that happens on your Pc and therefore updating it can really benefit your system’s performance. Just take into consideration that you probably must change out your motherboard as well when changing your Cpu.  Find out more here

If you are a passionate gamer like me you need to change your graphics card every few years to ensure that you can keep up with the demanding AAA titles, which require more and more graphical power. Just keep in mind that you should not buy a very capable GPU if you can not pair it with a Cpu that can keep up with the performance of the graphics card. CPU and GPU work together and therefore those two components should be equally strong to have the best gaming experience. 

3. Overclocking will not damage your desktop computer if you know what you are doing

It is a common belief that overclocking is something difficult, time-consuming and dangerous for the safety of Pc components. Overclocking has been described as a feature only very experienced Pc users should apply, as it can mess up your system.
While this is partially true, overclocking is actually pretty easy if you follow certain guidelines. If you want to check it how to overclock your CPU, click here to read my post about Cpu overclocking.

While it is true that heat and overvolting are the main causes for Pc hardware degradation over time, if you follow my guide you can overclock your CPU with safety. It will not only boost your desktop’s performance but also save you money as you can push performance out of your CPU to match a better CPU’s performance without having to buy it.

4. Choosing an appropriate Power Supply is the key to have a good and stable rig

I don’t know how many times I have seen or read about people who have spent more than 1000$ on a new system, only to go cheap on their power supply in order to use their budget for “more important components”. This misconception is not only wrong but can also damage your entire Pc. There are good and bad power supplies out there. Choosing the right power supply should be #1 priority for any PC builder. The power supply IS the most important part of your Pc and you should always see it this way. If you want to know how to choose a proper power supply check out my post here. Also, make sure to always choose a power supply according to the Tier 1 & 2 on  this list

5. Always protect your Pc with a good Anti-Virus

We always buy insurances for our cars, but most of the time we forget to “provide insurance for our Pc”. Protecting our system with a good Anti Virus is very important and should be done right after installing windows. Never use more than one Antivirus at a time as it can cause issues while one antivirus conflicts with the other. You should, however, use an Anti-Virus with an Anti-Malware program. I personally use Avast Premier in combination with Malwarebytes Anti-Malware Premium. You can get them both for a very cheap price on

You can also use the free versions of those programs, they are very good and offer great protection. However, the premium products offer even better protection. For example, Malwarebytes premium package offers real-time 24/7 protection from malware to spyware to cyber attacks. Note that these are the programs that I use. There are a plethora of products out there. Just find the best one that suits your needs.

6. 144 Hz monitors are vastly superior to 60 Hz ones

You’ve certainly heard it before: There is really no difference between high refresh rate monitors and regular ones because the eye can only see X fps (where at x you can put in any number you can imagine) First of all, the eye does not see in frames per second (FPS). Every eye is different and that is why everybody conceives high refresh rates differently. The truth is that the gaming experience you get on a 144 Hz monitor is totally different from a 60 Hz one. While there is no way t that I can prove you that right now, I recommend you find a 144 Hz monitor and see for yourself. If you intend to buy a great 1440p 144 Hz refresh rate monitor, check out my AOC Agon AG241QX review

You should know that, in order to take advantage of a 144 Hz monitor, your graphics card should be able to push 144 frames per second. Or at least more than 100Hz in order to feel a subtle difference. The vast majority of people see the biggest difference between 60Hz up to 100Hz, with 60-75Hz being the biggest game changer.

7. Always use a good quality Uninterruptible Power Supply (UPS)

You know the deal. You get on Pc Part Picker, choose your components, you buy them, they are delivered to you, you assemble your rig and you start working on your computer. Well, you have forgotten something important. You have not bought a UPS, a component which protects your system in case the electricity goes down or electricity spikes or even bad weather conditions, which can cause problems with the power delivery to your system. A UPS is essentially a battery for your Pc, which automatically switches to the battery ones electricity is down. That way, you have a couple of minutes to shut down your computer and you ensure that your Pc parts will not be damaged and that you save your documents so you do not lose them.

I would be really disappointed if I had to write this post all over again, only because it is storming outside and I could not save my progress before electricity gives up on me. Not only that but by the time electricity comes back, spikes are being produced, which can cause excessive damage to the components. Always buy a good PSU according to the power your Pc needs. Your power supply is a good indicator of how much power you actually need.

Furthermore, You can check out this program which lets you estimate what kind of UPS you need for your system. Power Supplies and UPS’s share the same principle: Never go cheap on them.

8. The way you install your  Pc fans, matters

In order to ensure the longevity of your system, you need good airflow in between your components. To get good airflow you need Pc fans. There is actually a big difference in regards to how you install your Pc fans. But before I tell you how you should install your fans, let us elaborate a bit more on airflow.

There are 3 types of airflow or pressure:

  • Positive Pressure/Airflow
  • Negative Pressure/Airflow
  • Neutral Pressure/Airflow

1. Positive Airflow

More air goes in than out. If you have more air getting into your case than out, you have positive air pressure. The advantage is that your case will accumulate less dust because air goes into the case only from certain areas of the case, (for example the Pc fans that are in front of the Pc). A disadvantage would be that temperatures would be a little higher than negative pressure because the air does not get out as much, which causes heat increase inside the computer.

2.Negative Airflow

More air goes out than in. If you have more air getting out of your case than in, you have negative air pressure. The advantage is that your case will have a lower temperature compared to positive pressure because the hot air inside the case has more ways to get out and therefore the temperature is lower. The disadvantage is that your case will turn into a dust accumulator, as air has to find a way in to make up for the air coming out and it usually happens from areas with no dust filters and therefore accumulating more dust.

3. Neutral pressure

The same amount of air goes in and out. If you have the same amount of air going in and out of your case, you have neutral air pressure. There are only advantages to neutral pressure and it is the ideal air configuration for your rig.

Now, you may ask: What is the best type of airflow? Certainly, neutral pressure is the way to go. However, it is not always achievable because many cases do not have spots for Pc fans everywhere. Most of them have two in the front, two on top and one at the back of the case. It is always a good idea to adjust the two front fans as intake fans, the two at the top as outtake and the back fan as an outtake.

This is a general rule and may not apply to you. In whatever way you choose to install your Pc fans, just make sure that you have installed them the way you wanted them. Most Pc fans today have an arrow which indicates the way the air flows. If you can not locate this arrow, the general rule is that air flows towards the X on the fan.

Air Coolers provide additional airflow to your case. A Cpu air cooler pushes the air towards the back of your case, where it gets out. Power supply fans actually work as intake fans, in contradiction to what most people believe.

There is no right way to install Pc fans. Either positive or negative make sure that you install your fans the way they work best for you.
