First of all, you might want to consider your needs. The good way to start is by asking yourself, what you will be using your new personal computer for. Think if you are planning to spend all the time browsing the web and using simple programs like Microsoft Office, then you will be good to go with a budget PC. Or, if you want to use some graphical and sound editing software, doing video editing for example or maybe you are a gaming enthusiast. This will most likely require much higher performance personal computer. Higher performance means higher cost, so you should be prepared to spend more money. To know how to purchase the right personal computer, it is vital to put into consideration the following components, and understand what they contribute to the overall performance of the PC:
CPU Processor is sort of a computer’s brain. A CPU performs all the tasks that need to be done, and it’s paramount to have multi-core processor if you plan to carry out multiple tasks at once. Web browsing and similar simple tasks require about two cores to run just fine, so the simple Core i3 CPU will be enough. However, smoother performance would be achieved by a better Core i5 CPUs.
RAM determines how fast each process can be completed. Every process requires some memory to be processed by the system, and RAM determines how much of that memory processing can be done in a single time unit. Simple tasks like web browsing can be easily done with 4 to 8 GB of RAM, even if it’s heavy web browsing. However, gaming and other heavy tasks require at least 8 to 16 GB of RAM.
Web browsing and other simple tasks can be done with built-in graphic chipset on a mainboard. However, any task that has any graphical requirements will need a separate graphical unit. More powerful graphical cards are never a bad idea since digital graphics are rapidly improving and so the requirements go up year by year. Although this may be the case, the mid-budget graphics card will get you through most of the graphical tasks and games on lowered settings.
This is not a hard choice. All you need to do is, think how much storage capacity you need and then buy accordingly. However, if you need your storage to allow you a superb performance, then you need an SSD (Solid state drive). For example, if the application you want to run requires lots of storage that means the storage performance will affect the task. SSDs have much better performance, but lower storage and they are more expensive.
