Hello

I am not the absolute expert, but I would say no.
More important is the mainboard you have. Since the card already supports PCI 4.0 you have a performance of 16GT/s with PCI 3.0 it is just 8GT/s. This would be a performance gain of about 50%. Read here: https://web.archive.org/web...

In addition, your Ryzen 3 also has AM4 like my Ryzen 7, so it's easy to upgrade if you need something stronger. However, my CPU is bored in most games :)

Hi. Depending on the resolution, a small performance loss (bottleneck) is to be expected. (<1440p). However, this is not very tragic.
PCIe 4 vs 3.0 makes no difference in performance (as long as you need the PCIe 3.0 x16).

However, I would not buy a 5700xt. Currently the problems are gigantic. Most 5700(xt) owners are experiencing crashes, black screens, stutters, etc.
I myself will probably have to return my card soon.
