What is the best GPU upgrade for Optiplex 3010 MT and what would I?
Honestly, what I recommend the most is a new platform. The 3010 is, put simply, terrible it's notoriously annoying to upgrade, and almost nothing is in a standard form factor. Try and get a supported motherboard and case for the specs you have, and then work from there (if you need help, shoot my a comment with the exact specs you have, and I'll help you pick). If you truly just want a gpu upgrade, there is one main thing of note the gpu market is entirely screwed up rn, and you could easily end up spending 2x more than what something is worth. With that being said, I would recommend either an older flagship (980 ti?) Or a newer low end card (a 1060/1050 ti would work well, or an rx 570).
