The RTX is a newer product, but the GTX cards are cheaper. So which one is better depends on your budget and how much you’re willing to pay for performance.
Choosing the right graphics card is all about balancing price with performance. Higher-end RTX models cost a lot more than their GTX counterparts, so they might be worth it if you’re running the most demanding games at high settings or like to stream video in 1080p60fps at 1440 hz. But if you just want higher frame rates on less graphically demanding games, then a GTX card should do the trick—and without costing as much money or taking up as much space inside your system.
