Sorry to but in on an ongoing conversation but I'm also interested in replacing my problematic fermi 450 gts. Is the 5770 really as easy as picking the ati-specific chameleon? I've already bought one card, I'm hesitant to pick another that I'm not sure about.
I could also get a 58xx series but it's considerably more and I'm not going to be a heavy user.
Anyway, I'm continuing to search on this, but if you have any input, it's greatly appreciated. Also, bow-ties are cool. (different doc but still)
