I am looking to upgrade my Dell Inspiron 531s' video card since the existing one sucks. http://www.google.com/products/cata..._catalog_result&resnum=1&ct=result#ps-sellers Since my computer is a slim computer the card has to be low profile. I have yet to find a 512mb card for it. Just tell me if this is good enough. And any brief instructions on how to install it inside the comptuer (not software, hardware installation). Thanks http://www.buy.com/prod/xfx-geforce...press-x16-video-card/q/loc/101/205097705.html here is another link, i don't know if a graphics adapter is the right thing, is it still a video card? Oh, and when it says 64-bit video card, do i have to have a 64-bit os installed?
