    OK I'm new to graphics cards. I've done every possible upgrade to the 2009 MP here.
    I've delidded and installed two 6 core Xeon's in it, and installed M.2 SSDs in the PCIe slots, and an USB 3 card as well.

    Looking at a MSI 580 locally for cheap, but I'm not sure if it's compatible?

    Anyone tried this one? worth attempting for $150 used?

    Do you have 2 SSD's installed in 2 PCIe slots? If you're using all 4 slots, you're going to have a hard time fitting that card into the 4th slot.

    They're M.2 SSDs on thin cards, the bigger USB3 card is in the top slot away from the GPU. It might be smart to start looking at room in the slots for sure. I'm not willing to give up the M,2 cards.

    That card may actually FIT better than the Sapphire Pulse RX 580 8GB model. Needed to remove two screws on the GPU in order to fit it properly and use all 4 available PCIe slots without issue. Regardless, the RX 580's are very large GPUs and poor overall fit when "stuffing" the PCIe slots full.

    See this thread for the modification I needed to do:

    The MSI RX580 you're showing does not look like it protrudes in the same way, which is probably a good thing. Hard to tell from the images about the fans protruding from outside of the plastic, however.

    Yeah it actually looks like the card is cut smaller towards the other PCIe slots looking at the photos on Amazon, the bottom photo shows a significant notch compared to the model you used, and at least in the photo shows nothing protruding past it. I think it's worth a buck fifty to find out. I'm not averse to heavily modding it.

    There's probably no way to get the startup screen on this card though. My old card isn't worth enough to sell though so backup etc.

    Just in case someone is considering the same MSI RX 580 Gaming X GPU, it's up and running now.
    It fit in just fine with all other PCIe slots filled. It requires a new cable harness, the older graphics cards run two 6 pin connectors to the card and this one is a single large 8 pin connector.

    Also, and this is interesting, OSX or the card itself does not like DVI TO HDMI converter cables, I first plugged in a single 27" LCD screen and it was bright pink. After looking around forever to see if it was a known issue I found one youtube video where a guy had the same problem and replaced the converter cable with a straight HDMI cable. Once the cable was replaced the card works like a charm!

    It must be the card then, or I can at least say it's not macOS. I have used a Sapphire Pulse RX580 with two DVI monitors. So one used the DVI output and the other used the HDMI output with an HDMI to DVI cable. Everything worked perfect
