Key points to consider when choosing a gaming graphics card will keep you from making the mistake of buying and save time and money.
CPU
An important aspect when choosing a gaming graphics card is what kind of central process is installed in your computer. If your processor is lower and older than the Intel Core i3 8100 or AMD Ryzen 3 1300x, then there is simply no point in buying an expensive and very powerful video card. The power of your processor will not be enough to make such a video card work to its fullest, to unleash its potential. In this case, we are talking about the concept of "bottleneck" or "bottleneck", which will act as the CPU. With this scenario, the highest possible purchase option for you is a gtx 1050 ti or rx 560. An AMD video card will be more difficult to find due to the recent mining boom.
Power consumption
Everything is simple here, the characteristics of each video card indicate how many watts it uses. This information must be compared with the power supply unit installed in your computer. Also note that the power of the power supply should be slightly higher than the declared power consumption of the video card (by 20-30%), so as not to force it to work at its limit and not overheat.
Connector and body size
Almost all modern video cards connect to a computer via the PCI-E port. When choosing a video card, you need to pay attention to what generation of the PCI-E interface is installed in your motherboard (2.0, 2.1 or 3.0). Ideally, it should be the same for both devices. Otherwise, the data exchange rate will be limited to the minimum supported by one device. That is, if you insert a PCI-E 2.0 video card into a PCI-E 3.0 port, then the maximum data exchange rate will be set by the PCI-E 2.0 standard.
It should also be borne in mind that most modern video cards occupy several PCI-E slots and that, for example, a Mini-Tower computer case will most likely not work because of its small size.
Type and amount of video memory
The most popular and optimal type of video memory for cards that are supposed to be used in modern games is GDDR5. GDDR3 is already outdated and shows itself normally only in projects that came out a long time ago. New products from NVIDIA have GDDR6 memory, and from AMD - HBM2.
For most games at a resolution of 1920x1080 (Full HD) and 60 fps, 3-4 GB of memory is enough. If we consider 4K resolution, then the minimum volume there is already 8 GB.
Monitor connector
The most popular multimedia standard is HDMI. Now all video cards, most monitors and televisions, as well as some other devices are equipped with it. If your monitor has a VGA or DVI connector, you will need to purchase an adapter.
