Great! Thanks everyone. Just found a pair of Kingston kvr1333d3n9/4g that I swapped out of someone's machine, so they'll be going in shortly!
Is there any real difference between an ASUS Phoenix 1050 Ti and an Inno3D card? Yes, I'm looking at PCCaseGear, I've had good experience with them over the last decade or so for other people's PCs, and the current components in my box.
Boot drive is a Seagate Barracuda, ST2000DM001, still reasonable for a physical drive but I guess a bottleneck for long-load time games. With the savings above, I could drop in a lovely Samsung 850 EVO 1TB, particularly if I can get it for less than $390! Yes, I'd love to get the Pro version, but $$$$. I just built a Sabre laptop with the Samsung 512GB 960 Pro NVMe and 1TB 850 Pro SSD. Wonderful stuff, but I could not keep them :(
