Do you really need an RTX GPU?

Whether or not you really need an RTX graphics card depends on what you plan to do with your computer. RTX graphics cards are designed to handle real-time ray tracing, a rendering technique that simulates the behavior of light in a scene to create more realistic lighting and shadows. If you plan to use your computer for tasks that require real-time ray tracing, such as high-end gaming or professional 3D modeling and rendering, then an RTX graphics card will provide significant benefits in terms of performance and visual quality. 

However, if you're not planning to use your computer for tasks that require real-time ray tracing, then you may not need an RTX graphics card. In that case, you could consider a less expensive graphics card that can still handle your specific needs. For example, if you're a casual gamer, a mid-range graphics card from the previous generation may be sufficient for your needs.

Ultimately, the decision of whether or not you need an RTX graphics card will depend on your specific use case and budget.
