I've had my 1060 for almost 7 years now and it's really showing it's age. Used to have and average of 20 to 30fps with it, despite it being a 3gb variant, but it is starting to show it's age.
Now I've been saving up money for a complete new setup but I need to replace my current gpu with urgency for reasons aside of p3d. So I've been looking for a new gpu, but I'm a bit on a budget.
I've seen people using P3Dv4 and v5 with a 1600 series card and getting 30+ pretty busy areas on medium settings. But I've also seen people using a 2000 series and 3000 series and having 30+ fps om medium to high setting.

My question is, which gpu do you use and can you recommend it for my situation?

You have to consider your CPU more powerful GPU could be held back with CPU limitations.

Could be the most popular gaming GPU in the future.

Before upgrading the graphics card you should also take into consideration your CPU, RAM, and power supply.

Benchmarks will be out soon and i think you will smaller die size of the 3050 will use less power than older CPU`s the PSU should be fine.

But if the computer has a slow CPU, what benefit will a faster GPU represent?

Eye candy that`s what GPU`s do higher settings as the GPU handles the graphics, at 1080p a 3090 is not much better than a 2080 in terms of fraps but you can run at 4K better than a 2080.
