Hello, I wanted to buy a new graphics card for my Dell Optiplex GX280 Small Desktop. The computer has a 210 Watt PSU, and I need a graphics card to upgrade to windows 7. Would this graphics card work http://www.newegg.com/Product/Product.aspx?Item=N82E16814130887&nm_mc=KNC-GoogleAdwords&cm_mmc=KNC-GoogleAdwords-_-pla-_-Desktop+Graphics+Cards-_-N82E16814130887&gclid=COfBpLLRlbYCFY9DMgodBnIABg, or this http://www.newegg.com/Product/Product.aspx?Item=N82E16814127705. If not can you give me some other suggestions? I am not a gamer, just want a graphics card which can run Windows 7. Thanks!
