Hello,
It seems there are numerous companies that make a "GT 610" graphics card. How/Where can I find a comparison to determine the "best" version/manufacturer to purchase??
all graphics cards use the same GPU have almost the same performance what ever who is the manufacturer, so i advise you to choose the cheapest gt610 or get a better graphics card if you really want something better.
here is 6670 for 65$ which its faster than gt610 http://www.newegg.com/Product/Product.aspx?Item=N82E16814102988
