So im looking at these 3 different cards, and two are alot alike but the cheaper one seems to have more to offer from what i can see in the specs. http://www.newegg.com/Product/Product.aspx?Item=N82E16814131458 these two only have 1 http://www.newegg.com/Product/Product.aspx?Item=N82E16814102962 this card, from what i can gather has two GPUs, and only 2gb of ram. so less ram then the two above. Is two GPUs faster then the two above? http://www.newegg.com/Product/Product.aspx?Item=N82E16814129183 this one has two DVI ports?
I would go for Sapphire HD7950 instead of the other two. The Sapphire is using a reference board so I can get an aftermarket cooler for this card. Otherwise, it could get pretty hot at load.
