7600GT, 7600GT KO, 7900GS, X1800GTO, X1950PRO or X850XT?

I would rather choose the X1950PRO, even though it doesn't overclock very well, it's performance is very close in many cases (But not all) to the 7950GT, and outperforms quite often the 7900GT (Often, like 40% of the games). And even though overclocking a 7900GS would give you performance, it can give you mixed results, some can overclock well, some others not, it is just like gambling.

My 7900GS won't go over 550 core with stock cooler and voltage.
