While choosing the graphics card or the CPU might seem like the most important decision, choosing the right motherboard is also a major decision that you have to make.
The size of the motherboard can dictate other parts of the build and limit compatibility with other components.
Some people tend to choose other hardware first and then pick a suitable motherboard, and then there are those that pick the motherboard first and build a system around it.
ATX is a common standard and is the largest of the three form factors that we are talking about here. ATX motherboards can house all the components that the other form factors can and can fit into an ATX case perfectly.
Both ATX and Micro ATX motherboards can support 4 RAM sticks. Talking about graphics card expansion and PCIe slots the ATX form factor can have as many as 7 slots.
Micro ATX boards, on the other hand, can only have up to 4 slots. This is something that you need to keep in mind if you are interested in using highspeed storage that uses PCIe slots like your graphics card.
So Is Micro ITX Smaller than Mini ATX?
Here comes the tricky part; Mini ITX is smaller than Micro ATX. By the names itself it can be quite hard to understand.
We have talked about the Micro ATX form factor above but the Mini ITX boards are even smaller and only come with 2 RAM slots. You can get 16 GB sticks in order to get to 32 GB of RAM so that is not an issue here.
If you are going with a small form factor build and are interested in getting the ITX board then keep in mind that smaller cases have little room for airflow and you will need to provide ample cooling in order to get the best possible performance.
This is not an issue with other form factors as you can easily add fans and liquid cooling very easily due to the additional space.
How do I Choose a Motherboard for Gaming?
If you need a small form factor PC that does not take a lot of space then you should go with the Mini ITX standard. If you need upgradeability and want to future-proof your build then ATX is going to be the best choice. If you are getting a killer deal of a Micro ATX board then you can consider that that as well.
Micro ATX boards are great value for money keeping in mind that you have enough PCI slots for 2 graphics cards and a few other components.
You also get 4 RAM slots. These motherboards are often cheaper as compared to ATX boards because of their high demand. You should go with the ATX motherboard if you are really going to use all those PCIe slots.

We have talked about the different motherboard sizes that are popular in the market as of today. Namely ATX, Micro ATX and Mini ITX and which one you should get if you are building a PC.
We have gone over the different features that each one has to offer and which one you should get if you are interested in building a gaming PC.
The problem with ITX boards is that you only have a single PCIe slot which is going to be used by your graphics card. If you need to plug something else into a PCIe slot then that is not going to be possible with a graphics card installed
We have also recommended some options for you to consider. Remember that the size of the motherboard does not impact the price. The price will depend on the quality of materials that have been used in order to make the motherboard.
If you are interested in buying a durable motherboard and are going to use it for a couple of years at least then you should spend a bit more in order to get a better quality motherboard rather than getting the cheapest one that meets your needs. At the end of the day, you are getting what you paid for.
