A couple of 3DMark scores hardly says anything about the cards' performance. Anyways, I think the only concern is whether or not the 76.8GB/s (or whatever) memory bandwidth will make the 5700 a better choice than 4870/90.
» Awaiting mid-range :) Thanks this is good stuff, been waiting for a while. This is why I come to FS, you guys understand the importance of 8xAA testing and that too with so many cards. Keep it up! Hope to see how the 9600GT does.
The game looks great and really immerse, what more could you want. Story is fun too with some interesting NPCs. :)
