I am looking to upgrade the graphics on a HP Pavilion a6114x Desktop. Information on this PC can be found http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01114300&tmp_task=prodinfoCategory&cc=us&dlc=en&lang=en&lc=en&product=3455704 and http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01077676&tmp_task=prodinfoCategory&cc=us&dlc=en&lang=en&lc=en&product=3455704#N52 . I don't intend to do any serious gaming, just basic computing and some programming. The reason I am upgrading is because I want to be able to have dual screens with extended desktop, as it makes programming significantly easier. Do you have any recommendations? I am not looking to spend too much... hopefully around $50-$75 for both a video card and a PSU. Everything is still original in the computer, with the exception of the 2GB of ram that I added.
