If you are looking into purchasing a powerful gaming laptop or building one, then you ought to pay attention to the graphics card. It is an important component for every gaming PC. However, getting the graphics card can be a tough challenge because there are many of them to consider. Fortunately, it does not have to be difficult when you know your PC requirements, your performance goals, and budget. These are some of the things to consider when purchasing a graphics card.
It can be quite frustrating when you open the case to install a new graphics card, only to discover it is a few inches longer. Before you choose to purchase, you should do your research find the amount of physical space your PC can offer. Also, you have to take note of the power supply. For instance, how many amps can the unit supply? You should cross-check the information with the graphics card you need to purchase. If your computer cannot handle it, you need a graphics card that needs less power or even consider a power upgrade.
The system dictates the type of graphics card you should purchase. Understanding your system’s limitations can save you headache and money. For instance, if you are running an old dual-core CPU such as Celeron or Pentium, it may not keep up with the high-end graphics cards. Thus, you should go for mid-range cards that can even help you save money. Another vital thing to consider is the display. If you are using an old resolution of 1280 x 1024, you do not need high-end graphics.
Memory and Bandwidth
Most people will tell you that bigger graphics cards deliver better performance. However, that is not the case. Unless you use it with the ultra-high resolutions, like 4K or multiple monitors, the amount of RAM will not make any difference. Moreover, most high-end graphics cards come with their memory. The fact that memory bandwidth is an important determinant means it is a good idea to choose GDDR5 for improved performance.
Like the CPU, GPU generates a lot of heat for the work it does. The amount of heat is shown by TDP value. Also, these values indicate the amount of power needed to keep the GPU at the optimal temperature. It is advisable to go for a graphics card with the smallest TDP value.
