I want to put 2 rx 480s in Crossfire. I have 2 PCIe 3.0 slots one of them is 16x the other is 4x. Will I see bad performance out of running one of the 480s on a 4x slot? Or will I be fine?

Video cards have yet to need any more than PCI-Express 1.1 x8, which is equivalent to PCI-Express 3.0 x4. So you're fine.

Why? You are better off selling the 1st 480 and, with the money you'd spend on a second one, get single 1070. Avoid multi GPU solutions if you can avoid them.

Get a 1070 instead.

Make sure to quote me or tag me when responding to me, or I might not know you replied! Examples:

Interested in computer architecture? Still in middle or high school? P.M. me!

 

I love computer hardware and feel free to ask me anything about that (or phones). I especially like SSDs. But please do not ask me anything about Networking, programming, command line stuff, or any relatively hard software stuff. I know next to nothing about that.

I have a blog! And a list of guides I've posted

Crossfire on the RX 480 is anything but polished. Save yourself a lot of frustration and get a strong single card.

 

 

 

If anyone asks you never saw me.

Get a single GTX 1070 because some games have really bad multi-gpu scaleing
