RX-580 on PCIe 1.x

[Azukae]

Hello,
I'm running a pretty old build right now

Gigabyte GA-EX58-UD3R
Core i7-920
AMD HD 6950

and would upgrade my gpu for something like an RX-580 which run PCIe 3 but my 6 years old mobo seems to only hold what i believe is PCIe 1 slot :

"2 x PCI Express x16 slots, running at x16
(The PCI Express slots conform to PCI Express 2.0 standard.)"

I read PCIe3 can run on 2 or 1 and max bandwidth might not be reach.

My question is then how bad would it be ? Bandwidth issue y/n ? Power issue y/n ?
I do believe my CPU can still handle it.

Edit : Alright, my bad, after further investigation it seems i'm running PCIe 2, i guess it's good then.
A compatibility confirmation would ease me still.

You're right😀

The 580 won't even come close to having any bandwidth issues. The same applies to the 1080. Try and go SLI and there may be issues. With the CPU in play that won't ever happen because if the bandwidth wasn't an issue the 920 would be the ball and chain slowing down the show.

Alright, thanks.
