I am running a Dell Optiplex 780 Quad Core PC and want to upgrade to a decent graphics card. I am not a die hard gamer but enjoy playing a few of the fairly new games once in a while. Can you please recommend a decent "QUIET" video card that would fit my system? I foolishly bought a GT 220 [?] but it was so loud I had to take it out. Can not afford more than around $125. Any advice would be appreciated. Thank you.
