I was going to get this: http://www.newegg.com/Product/Product.aspx?Item=N82E16814150443&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-RSSDailyDeals-_-na-_-na&AID=10521304&PID=3463938&SID= but then I saw other 5870 cards that were a much higher price, such as http://www.newegg.com/Product/Product.aspx?Item=N82E16814125323&cm_re=5870-_-14-125-323-_-Product and http://www.newegg.com/Product/Product.aspx?Item=N82E16814102872&cm_re=5870-_-14-102-872-_-Product . Is there any difference between them, or are they the same card? If not, which 5870 should I get if I want one that's quiet and performs well? Not planning to overclock.
