Answer» I inquired on another forum about what graphics card would work best on my Optiplex 360 and he mentioned to make sure I didn't have a UEFI - Legacy conflict between the bios and the graphics card I want to put in. https://www.amazon.com/ViewMax-NVIDIA-GeForce-Express-Support/dp/B00WNO327Y/ref=sr_1_2?ie=UTF8&qid=1486619989&sr=8-2&keywords=gtx+750+ti+1gb Can someone explain this to me?Somebody told you a new graphics card might not work on an old computer due to a conflict with the legacy BIOS?
