great work here..
I came into this forum to ask about buying a 4770 vs 4670 vs 4850.
I got some seriously good information from here, even though it seems to disagree with a few things I've found on other sites - like the 4670 performing so poorly vs 38xx series.
still, its the most helpful thing I've found in my searching.
Can I ask why you haven't included the 4770?
I found this in the first post
Q: Why is card "X" not listed?
A: Because I'm lazy
maybe you can remember the 4770 on the next lazyless day you have.
