Is PCIe Gen 3.0 alright for gaming?

Build Upgrade

I got GIGABYTE B660 GAMING X DDR4 mobo and the PCIe Gen 4.0 slot is taken from a 2tb ssd. I want to expand my storage with another 2tb ssd but I only have PCIe 3.0 slot available. Was thinking of getting SAMSUNG 970 EVO 2TB. As far as I'm seeing the ssd I have now is about twice as fast as the Samsung one. Would this make games load a lot slower or should I be fine?

Also this is from the spec sheet of the mobo:

1 x M.2 connector (Socket 3, M key, type 2260/2280/22110 PCIe 4.0 x4/x2 SSD support) (M2P_SB)1 x M.2 connector (Socket 3, M key, type 2260/2280/22110 PCIe 3.0 x4/x2 SSD support) (M2M_SB)4 x SATA 6Gb/s connectors

Does that mean I can have 2 PCIe 4 SSDs?

​

EDIT:I spoke to the customer support of the local website I order parts from and they told me I can put in a 2nd PCIE 4.

Full specs of the mobo:

Is this true?

It says I have PCIE 4 on the CPU and PCIE 4 to the storage. What does that mean?

1 PCIE 4.0 and 1 PCIE 3.0 is what the motherboard supports.

PCIE 3.0 is fine for gaming, in real day to day operation you won't actually notice the extra speeds unless you're doing a workload that actual requires it, gaming is not one of them.

That's good to know then. The PCIE 3 is cheaper anyway. Is a 6gb SATA drive better than a PCIe 3 SSD? Since the speeds on the Samsung one I'm looking at are 3500 MB/s read and 2500 MB/s write which is less if I'm assuming right?

I'm using a PCIE 2.0 slot and get 60+ fps so I'd reckon that PCIE 3.0 is good for gaming.
