From smartphones to computers, the technology we use day-to-day is flanked by myths that never seem to disappear. These misconceptions are somewhat plausible since they all have a grain of truth to them. Some were even true in the past.

Try not to mind these myths, especially when you’re shopping for a new computer. Else, you’ll never buy anything that can fully satisfy your needs. Below are five most common myths about computer hardware that won’t just go away.

1. More RAM means a faster computer all the time.

A hardware with more RAM doesn’t hurt. However it doesn’t mean that it can always help, too. Buying a computer with more RAM will only help if your PC requires extra random access memory. If your PC works fine with an 8GB RAM, there’s no need for you to insert another 8GB for additional cache space.

If you’re thinking of upgrading your computer with extra RAM, ensure that your PC truly needs it. You can do this by keeping track of the level of memory being used. Upgrading your RAM will only help if you use sizeable virtual machines all the time or play hardcore PC games.

2. More cores means a speed up computer.

With regards to the CPU of your computer, or any device for that matter, the number of cores is not the single most important element of the machine. Every core is an independent execution unit. Multiple cores enable your PC to work with numerous various applications all at once.

However it’s not only about the number of cores your computer has. For instance, if you’re running a single-threaded program, it’s only possible to operate on one core each time, so a speedier 4-core CPU will still operate faster than a slower 8-core processing unit.

3. 64-bit Software loads quicker than a 32-bit software.

Most CPUs now are 64-bit. Thus, the majority of computer OS matches said units. But still a great deal of programs runs on current operating system like Windows are still 32-bit. In reality, that’s not as bad as it may seem since 64-bit software is not always faster and better than 32-bit program.

Yes, 64-bit offers many benefits like enabling apps to work with more RAM to increase security. But that doesn’t mean that it loads applications faster. Apps that are computer-intensive may see significant changes, but not every program will.

4. A Mac is always pricier than a PC.

Compared to the low-end Windows computers and Chromebook, Mac computers are more expensive. But when you compare the price of a Mac to a higher-end PC, you’ll see a comparable price list and almost identical specs.

5. A build-your-own computer is unfailingly cheaper than a brand-new PC.

Contrary to what others may believe, building your own computer doesn’t always mean savings. In the past, it certainly would. If you’re planning on building a high-end gaming computer, going DIY may save you some bucks. But if what you need is a just a regular desktop, buying a pre-built computer is better, operation- and financial-wise.

These are just five of the most common misconceptions about computer hardware. But many experts who sell electronics stress that these are the five you should always remember if you’re shopping for a new PC.
