Explain your vote. Also if you have any ideas/rumors/speculation on clocks and shaders, out with it! I predict the 5770's core will be as powerful as a 4870 or even 4890 but it's memory bandwith will be much less than a 4830. Therefore, I voted equal to a 4830 in performance. But I could be wrong and the 4830 may still be faster because it has much more memory bandwith!
