Exactly, you should know this from the model number.
100-900, the biggest the number is the better.
Even if they number is bigger like here "8" and "7"
i am not sure of the overclockability of 7950gt, but my 8600gt scored over 6000 in 3dmark06. If I push my cpu and add better cooling for my graphics card, I think I can go beeter. Does 7950 overclocks better than 8600gt? Well, we just bought a computer with E6600 and 7950Gt, so it is out of question which one we are going to get.
8600 GT can go upto 700mhz.Though it's not my personal experience it's shown in a website where the guys stretched it upto not exactly 700 but close to it.
