Buying Guide

The choice of motherboard is an important step in PC building. You can not ignore the fact that compatibility between your motherboard and processor is mandatory. If the motherboard can not fulfill the processor’s needs, your processor becomes worthless. Despite the above guide, a buyer can still get confused when selecting the best motherboard. This is why we have come up with a list of certain things that you need to be aware of. 


The first and most important thing you need to be clear about is whether your processor is compatible with your motherboard or not. The thing here is processors come in different versions, and not every version does well with every motherboard. So before purchasing, take a quick look at the processors your motherboard can support. 

RAM Capacity

Memory is something that varies from user to user depending upon the requirement. Where a majority of people go for high memory, some just settle for smaller RAM size. So when purchasing the motherboard, sort out your memory requirement first. 


BIOS is an in-built software installed in every motherboard. The function of this software is to detect all the components mounted on the motherboard and form a connection between them. The point is that BIOS needs to be updated regularly. If your motherboard is old and you are opting for a new processor, ensure that the BIOS installed in the motherboard is compatible with the processor. Else your motherboard will fail to detect the processor. 

Frequently Asked Questions

1. Is the Ryzen 3900X a good choice for gaming?

Yes, the Ryzen 3900X is an excellent purchase for gaming lovers. Owing to the 12 cores and 24 threads, this processor is well suited to handle heavy data loads. However, keep in mind that pairing it with an equally capable motherboard and graphics card will amplify the powers of this processor. So, with a low-end motherboard and graphics card, this processor may still underperform.

This depends on the user. Typically, the stock CPU cooler does a really good job of keeping the processor at a safe temperature. This is why an average user does not need an additional investment in a cooler. However, if you intend to overclock the CPU more than usual, you might need a more effective cooler to regulate the temperature more effectively.
