This card will cost you a little more, but will perform a lot better than the 8500 gt. If you are wanting to game, this would be much better. It should run on your stock PSU as it does not require an external power connector. The 8500 gt should work as well, but for the money, no contest, grab the ATI 4670.
I bought an Inspiron 530 recently. I ordered with an integrated Intel GMA 3100. When I called Dell tech support and asked about a 512 MB card, I was told that I may have to upgrade the power supply. He suggested me to buy Nvidia 7200 GS, but I wanted a better performing card. I prefer Nvidia cards because of better Linux support.
Can sungkum or somebody suggest to me better performing cards(with out upgrading the power supply)? Thank you.
