A hastilly drawn out plan on how to research components for your new computer, whether it is to build or to buy, and a resource to bring things together much easier than trying to figure out why some pieces go together and some do not.
When you are first looking at building a computer it is very important to know why you are building it. This likely sounds like an obvious thing, but can be easily overlooked as you are going into the process. It's easy to be diestracted by bigger and better when you really just need a simple computer for writing documents, or trying to find cheap alternatives when you should be finding a good quality component for your graphic design business.
The main parts you will be looking at include:
The processor will determine the performance of your computer as well as the size of you computer. You may want to map out what processor is right for you before looking at motherboards as everything that comes after will be determined by what motherboard you pick, and what motherboard you pick will determine what Processors you can have.
This is the component your whole computer is built upon, as stated before, what you pick here will determine what you are able to pick for basically everything else.
Most people will likely connect a graphics card with playing computer games, how they look and the speed they play. While this is probably mostly the truth, you should also take into account anything that takes it's toll on the computers performance, such as photoshop and 3d object creations.
Just get 8 gb of memory or more. With the applications that run on computers anymore and the amount of tasks most of us are using at the same time it's good to have that extra memory for those small tasks that add up.
Ensure your case size can accomadate all the items you have gathered so far, and that it can accomadate a powersource that you need for all your components and cooling fans
Get a hard drive that can keep up with you. An SSD harddrive is faster and better than a regular one.
