When you purchase a computer such as a Dell desktop PC, it already comes with onboard graphics processing units or GPU. This onboard GPU allows your computer to render graphics such as image, animations, or video onto your monitor. However, most integrated GPUs are not powerful enough to run the most graphically demanding games, such as Assassin’s Creed: Odyssey and Shadow of the Tomb Raider. Likewise, onboard GPUs do not have their memory and thus will use part of your computer’s main RAM, meaning if you have a PC with 8GB RAM, your onboard GPU will use part of that 8GB RAM for rendering images. It is therefore important for you to purchase a separate GPU for your computer. Here are some of the things to consider when choosing a GPU to install.
GPUs or graphics cards come in different sizes depending on the cooling module it comes with and its profile. Your choice of graphics card will depend on the size of your PC casing. Many PC cases do not have enough space to accommodate the largest GPUs, especially those that take up three expansion slots. If you have a slim Dell desktop PC, then your GPU choice is limited to those with a slim or low profile. On the other hand, if you have a larger ATX PC casing, it is best to choose a bigger GPU since it will have better cooling features and run quieter.
Another thing to consider when choosing a GPU is its video outputs. Nowadays, most GPUs out in the market have at least one display port and one HDMI connector. Some high-end GPUs may have two display ports to choose from, such as having a VGA port and a DVI-D port. When choosing a GPU, make sure that it can connect to the monitor you are currently using. If not, then you may probably end up buying a new monitor or replacing the GPU, whichever is more economical. Likewise, your choice of GPU will depend on your monitor setup. If you are running a dual-monitor build, then you either need to purchase a single graphics card with two or more of the same video output ports or purchase two graphics cards for your PC.
Large graphics cards that have their cooling units may require two 8-pin PEG connectors to function. You may end up upgrading your existing power supply if you opt for a graphics card that will need an additional power supply for its cooling units. Likewise, a GPU with built-in cooling units will require a power supply unit (PSU) with larger power output such as 700 watts and higher.
GPUs come with dedicated memory ranging from 2GB to 12GB of RAM. Higher video memory will allow you to play graphics-intensive games at higher resolutions. If paired with a powerful Dell desktop PC, high memory GPUs will allow you to play games at ultra-high-resolution settings giving you the added gaming experience. Likewise, higher memory graphics cards may already have anti-aliasing features that remove jagged or pixelated textures to improve video quality.
When purchasing a graphics card, you should also consider the brand. Nowadays, only two major brands are competing in the graphics card market, namely: NVIDIA and AMD. Each graphics card manufacturer has GPU models that are similar in performance. There are many debates on which brand is better, so it is important to do your research on which brand of GPU to choose.
To sum it all up, if you have a Dell desktop PC, you are already capable of running most apps by using its integrated GPU. However, if you need to improve your gaming experience, you need to purchase a separate graphics card.
