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? https://www.amazon.com/dp/B0781XS6QS/ref=psdc_284822_rv_t1_B06ZZ6FMF8 Anyone tried this one? worth attempting for $150 used?
