Hi. I'm trying to decide whether I want the Radeon HD 7870 - (http://www.newegg.com/Product/Product.aspx?Item=N82E16814125418) or the Radeon HD 7950 - (http://www.newegg.com/Product/Product.aspx?Item=N82E16814125414). I realize the memory on the 7950 is 3GB at 384-bit, so judging by that, it should be much faster than the 2GB at 256-bit on the 7870 (right?). Although, I looked at benchmarks and it only seems to give about 2-5 fps more than the 7870. To me, that small frame rate increase isn't nearly enough to be worth $60 more for the 7950. Can anyone else justify this price difference?
