Solved! Is Ryzen 5 5600 and RX 6600 a good pair? (on a PCIe 3.0 MB)

I'm upgrading some of my PC components I will be adding the Ryzen 5 5600 on my old B350 MORTAR motherboard and will be pairing it with RX 6600.
So two question:
1- Is there any bottleneck happening?
2- Any real disadvantage from using a PCIe 4.0 cpu and gpu on a PCIe 3.0 motherboard?
Thanks.

Your combo is the bang for buck champ at the moment. I have them paired together and modern AAA blockbuster 1080p gaming is stupid good for the money. Older games you can run at 1440 or 4k. The 6600 is the bottleneck almost always, but that is the bottleneck you want i.e. GPU limited.

The difference between PCIE4 and 3 with your AM4 setup is nominal. 4%-5% in the titles where it even matters; nothing you will ever notice. I still have it in a B450 mini-ITX setup so can confirm it makes no real world difference.

Well that is the most perfect answer I have ever received, thank you my good sir.

PCIE-3.0x8 is plenty to run that 6600 to its full potential. Where you run into problems on PCIE-3.0 is on 4 lane cards like the RX 6500 XT. And that Ryzen 5 5600 for $118 is maybe the best cpu deal I have ever seen, it's a no-brainer upgrade if you're running something like a Ryzen 1600, 1700x, 2600, hell at that price it's probably even a good upgrade over a 3600 or 2700x. Plus the two Uncharted games you get with it if you buy off Amazon or Newegg are both awesome.

Thanks a lot for the replies yeah I did get the 5600 and the rx6600 today and installed them on my B350 after updating the bios all went smooth thank god but my ryzen 5600 tend to run pretty hot like 50-55C idle and 85C when gaming is that normal and I'm using the stock cooler.

The stock cooler isn't the greatest but it will suffice. Those temps are probably a little higher than I would expect, but without knowing your case and fans arrangement it's hard to say. For about $25 on Amazon you can pick up the ID-cooling se224 that would be a definite upgrade.
