I already know that the card will work on a PCIe 2.0 board. What I'm curious about is if the PCIe 2.0 bandwidth would be a bottleneck to the GTX 1650 GDDR6 card. Or not a concern with this low end card?

If not a concern, what about a RX-570?
 
Where does PCIe 2.0 start to become a bottleneck? By that I mean what level of card begins to bottleneck at 2.0?
Depending on your tolerance of how bad things are, an RTX 3080 only loses about 25% of its performance on PCIe 1.x x8, and about 10-15% on PCIe 1.x x16 (https://www.techpowerup.com/review/nvidia-geforce-rtx-3080-pci-express-scaling/27.html)

There's only three things a video card needs the PCIe bus for in-game (and not on loading screens)
  • Receiving render commands from the CPU (higher FPS = more commands = higher bandwidth needed)
  • Texture streaming
  • VRAM swapping

That is the same site I had my information from the 2080ti looks like the first card to loose some performance but only 3%.
Funny how I remembered that for a couple years.
