Gamers barely had time to catch their collective breath after the cryptocurrency market tanked before Nvidia launched its GeForce RTX series, which in turn presented a conundrum—pay a premium for one of the newest and best graphics cards on the market, or save some money and invest in 'old' technology. For many, the answer was simple.

Nvidia would later lament that RTX card sales had not met expectations, due to a combination of price and a lack of games supporting RTX's staple features (real-time ray tracing and Deep Learning Super Sampling). But then came along the GeForce RTX 2060, making the path to RTX more affordable. You might now be wondering, should you buy a GeForce RTX 2060, or save a few bucks and buy a previous generation GeForce GTX 1070.
