Hello, i'm trying to run Adobe Premiere Pro on my Dell Optiplex 990 sff and have an old NVIDIA GeForce G100 installed in it along with about 8 GB of ram and a 250 watt max PSU. I am wondering what is the best graphics card and power supply, (or just a graphics card on its own) I would need to run Premiere Pro to a decent level on my PC. Any help?
