Why Should You Invest in a Quality Motherboard?

You’ve just bought your PC, and everything seems to work, so why should you buy a new motherboard?  A motherboard determines the computer’s ability to perform and connect to other components.  

Moreover, the motherboard will play a role in the work you intend to do. For example, if you plan to edit 4K videos or play modern game titles, you need a powerful motherboard with great overclocking ability.

Some of the  other reasons you should get a better quality motherboard include:

Reliability and Stability

The right motherboard provides stable performance, and you don’t have to worry about network or connection issues. Instead, you can rely on your PC, knowing it won’t hang or crash when dealing with a considerable workload.

Quality motherboards also provide stability by ensuring that your work is protected and you can quickly recover it. That’s because the best motherboard comes with graphics cards, ports, and processors.  All these components are meant to keep your PC reliable and stable.

Enhanced Performance

Investing in a quality motherboard allows your computer to process various functions. For example, if you’re into gaming, you’ll need a motherboard with excellent processing power and speed.

Likewise, content creators and video editors will experience improved performance with a motherboard with overclocking capabilities and more cores/threads.

Upgrade Your Computer

Another reason you should consider getting a new motherboard is if you plan on upgrading your PC. Having an outdated motherboard may inconvenience you when playing the latest games or editing high-resolution videos.

You don’t have to get rid of your PC, all you need is a new motherboard, and you’re sorted.

Several motherboards are designed to work with the Intel Core-i9 9900K, but how do you decide on the right one?

Below is a detailed buying guide on the essential factors to evaluate when comparing the available motherboards in the market.

Compatibility With The Processor

The Intel Core i9 9900K doesn’t work with any motherboard. So you need to find a motherboard that is compatible with your processor. With an Intel processor, you’ll find that most use the LGA socket.

The Form Factor of Your Motherboard

Form factor refers to the shape, size, and physical attributes of a motherboard. All these play a role in connectivity. Ensure that you get a motherboard that fits your PC cabinet. Some of the standard sizes include the Mini ITX, Micro ATX, ATX, and EATX.

Compact PCs work best with a mini ITX board, while larger computers can work with ATX or EATX as these options can accommodate a big PC and provide several connectivity options. They come with better I/O selection and PCle lanes.


VRM or voltage regulator module is a vital part of any motherboard as it contributes to the stability of your PC. The motherboards listed above have significant VRM phases, which means you won’t encounter stability issues during operation.

RAM Capacity

The more RAM you have, the better the processor’s performance. That’s why you should check the RAM capacity when purchasing a motherboard. Most motherboards have a RAM capacity of 64GB, but you’ll find some that have 128GB RAM.

Modern motherboards use DDR4, which is the latest memory technology. You’ll also find some with Intel Optane technology, which is different from the mechanical memory type.

Slots Available

Are you looking to add other components like a graphics card or sound card to your computer? You should pay attention to the number of expansion slots available. You’ll need PCI-e slots to install these components. 

Fortunately, most I9 motherboards come with several expansion slots that you can use for your GPU, RAM, DIMM, and more. The right motherboard should also have fast and stable WiFi connectors.

PCle connectors are also critical when building your PC. these slots determine the number of graphic cards you can use at one and the bandwidth speeds. You’ll find some manufacturers install metallically reinforced PCle slots as some graphic cards are heavy.


A processor like Intel Core I9 needs a powerful motherboard. Getting a compatible chipset is something you can’t ignore.

Most motherboards use the Z390 chipset as it supports memory overclocking and overclocking, depending on your needs. Z370 chipset is also compatible with the I9 processor and only needs a BIOS update to work.


The socket used by your processor should match the socket of your motherboard. The best motherboards for i9 9900 come with the LGA1151 socket. This socket can handle heavy tasks and the latest titles.


BIOS is a small software or operating system of the motherboard’s chipset.  Having an updated BIOS allows you to access the latest features and get maximum performance from your computer.  

Check if your preferred motherboard’s support site provides regular BIOS updates as they are essential for system stability.

Overclocking Capability

You should check your motherboard’s overclocking ability if your goal is to get the best performance from it. This feature eliminates lagging and helps you get the potential power of the slotted components on the motherboard.

The boosted frequency is critical when coding, gaming, or rendering as they make the process fast. If you’re cross-checking, you’ll need to explore VRMs, the BIOS profiling setup, and the attached heat sinks.

Storage Options

The best motherboard for an i9 processor needs to have the option of installing several storage options.  Entry-level motherboards have SATA ports for storage, but modern motherboards come with NVMe storage ports that provide quick speeds thanks to PCLe connections. 

With the i9 9900k, you need a motherboard with at least the Z390 chipset with 24 PCle lanes.  Get a motherboard with max PCle lanes as they are redistributed among other ports like the USB, M2, SATA, etc. Always check the available storage options and the types offered before purchasing a motherboard.


You can tell a lot about a product by the manufacturer’s name. Ensure that you pick a motherboard from a reputable brand known for quality PC parts.  Brands like MSI, Gigabyte, and ASUS are trusted and provide a guarantee or warranty for their products.


Another critical factor that you should have in mind when shopping is the price of the motherboard. As a beginner, you can get an affordable motherboard with the necessary features for your work type.

However, if you’re a content creator, video editor, or gaming enthusiast, you need a powerful motherboard with features to simplify your work. These boards will be costly, but you won’t need to upgrade soon. Instead, consider the motherboard a long-term investment that will provide value for your money.
