Hi . If someone would help me it would be much appreciated. I have a Dell Optiplex 9020 core i5 3.30 Ghz desktop PC 4th generation with 4GB RAM. I want to get a good graphics card installed. I like the Geforce GTX 750 Ti and wanted to know if I can have it installed it in my PC. I am not hardware savvy and do not know if any other hardware is required in my PC to properly run it . I do not know what my computer's power supply is, or if that is necessary for the card. Can anyone advise if my computer is capable to handle the card without creating any problems. Thank you.
