Top video cards that you should not take from the "secondary"

In view of the inflated prices for new video cards, most gamers prefer to look at the used components market in search of the best deal. The success of the transaction includes many factors: the chosen model, its price, condition and the presence of defects. IT enthusiasts know for sure: buy video cards today it is not as easy as it was before the era of mining, besides, it can be even more difficult to find the optimal components from the used market. That is why today we will consider a list of video cards that are categorically not recommended to be bought by hand, even if they are given at an attractive price.

Radeon RX Vega 64/56

Old AMD flagship graphics cards are rightfully called home heaters. To cool the powerful processor in the reference models, turbine-type COs were used, while partner solutions, not without exception, were equipped with a water type. In the first case, users received a real screaming vacuum cleaner in the system unit, and in the second, a lot of trouble when completing the case with a water pump and a radiator. The Radeon RX Vega 64/56 models used HBM2 graphics memory, which is located dangerously close to the GPU on the same substrate, which created additional overheating problems. In addition, the HBM2 memory type is especially popular among miners, so with a probability of 100%, the Radeon RX Vega 64/56 models were used on mining farms, that is, you buy a video card with a high risk of GPU “dumping”, a temperature of about 90 degrees and power consumption over 300 W.

RX 5700 XT

Overheating problems have not bypassed the more modern custom model Radeon RX 5700 XT. Initially focused on games at a resolution of 1440p, the video card from the “reds” warms up to 75 degrees on average, but in some areas you can fix the value of 90 degrees Celsius. Remembering the love of crypto miners for high performance AMD products, the combination of high heat and 24/7 operation will lead to the slow death of the GPU soon enough.

GeForce RTX 2080

NVIDIA products should not be excluded from the “black list” of secondary video cards: Turing flagships are very popular in rigs, because they were purchased at low prices after the announcement of the 3000 series and have been actively used for more than two years now. In addition, GeForce RTX 2018 models and Ti modifications released before December 2080 are more prone to various breakdowns and problems. You can calculate the earliest revision of the GeForce RTX 2080 by serial number.

Flagships Ampere and Pascal

Flagship graphics cards NVIDIA GeForce GTX 1000 and RTX 3000 are characterized by increased attention among crypto miners, and the 1080/Ti models are even further heated to extreme temperatures. The Internet is full of examples of how the GeForce GTX 1080 Ti burned out a few seconds after being turned on.


If you decide to buy a video card from the secondary market, then follow the basic recommendations:

  • Choose a GPU with moderate power consumption. Heat is the main killer of GPUs and memory.

  • Avoid flagship models popular among miners.

  • It is better to pay attention to video cards from reliable vendors with an efficient cooling system.

  • Accept the fact that you will never know the real history of the use of the video card or the fact that it somehow took part in the mining of cryptocurrencies.

  • When buying, it is important to inspect the product for defects.

  • Be sure to service after purchase.
