[citation][nom]dalauder[/nom]Radeon said that the 5770 wouldn't be replaced immediately--that's why they didn't use the 6700 series and used the confusing 6800 name a while back. Besides a 5850 is down to the release price of a 5770. And that's a powerful card.[/citation]
Powerful, but not quite.
I had both a 5770 and 4670, and I loved them. Performance is nice, but I'd rather not wake the neighbor.
