you seem to have mislabeled that 7950gt as 512mb. in the link it is 256
if it were 512 it would have some advantages. the 7950gt is slower, but it does have more pixel pipelines. the ati card in turn has more pixel shaders so its up to you.
Or for more games, this 7950GT review which includes 4-7950GT's at different clock speeds ( 1 reference, 3 overclocked). If you look at the X1900XT 256MB, it's the same as the X1950XT but with 350MHz slower DDR. Obviously, (like it does in the other link above) the X1950XT with the faster memory will beat the X1900XT, so you can get an idea as X1900XT beats the 7950GT.
