Lately we’ve found that the realm of graphics cards is experiencing quite the conundrum. The good news is that Nvidia’s sales are up, which means graphics cards are in high demand. The bad news is that no one can buy a graphics card (GPU) at the manufacturer’s suggested retail price (MSRP) right now because of cryptocurrency miners. For those unfamiliar, a bunch of people are trying to make a quick buck buying up all the GPUs that they can with the intention of using them to mine Ethereum and Dogecoin. 

In other words, gamers are faced with a dilemma. We can wait until the next generation of graphics cards to strike down like lightning (or Volta), or we can buy the best GPU for gaming right now at a premium. Who knows? Maybe you’ll be able to sell it to a crypto miner for a profit in the coming months. In the meantime, however, you can use the graphics card of your choosing to run the latest, most demanding games, such as Kingdom Come: Deliverance and Metal Gear Survive, in addition to games that are actually good like Final Fantasy XV.
