MP 1,1-5,1 Single PCIe slot graphics card for macPro5,1

That looks great! Thank you.
My Mac Pro currently has an MPX W5500X installed, so this would be (essentially) the same card.
Just to clarify, will this video card work natively out of the box or will it need to be flashed?

You are very lucky with your purchase. The W5500x is substantially better than the super ancient RX 580 baseline card.
With the MP7.1 there is no flash required any more if you stay inside Apple recommended gpu spectrum. The only item you will need is the Belkin Mac Pro cable kit to connect the power.

No need to be flashed. Be aware that you can't route video signals without a MPX GPU.

Only if he is going to remove the factory MPX GPU and install a third party one instead.

This computer will be run headless, no need for video routing.

That is my intention. I plan on installing two Promise Pegasus R4i units as a RAID-50.
