My sync is bang-on: no delay and no dropped frames. While it's possible I'm just not sensitive to it (I'm much more audio-centric) I have spent quite some time looking for it, as well as using the diagnostics overlay to watch for dropped frames with various settings.
It is absolutely a shot in the dark - based on anecdotal evidence (user reports) that 24p sync is good with AE. Being a total re-write of the audio code, any sync improvement was accidental only. There is no "aha - there it was" line of code anyone can point at. Part of the issue is that none of the devs can repro this problem. I've been in team chats of the type "do you get it? no? I don't get it either. Perfect here, does anyone see it?"
I've never thought it was a horsepower issue. Much more likely that it's a slight mismatch in sync between video and audio clocking frequencies, whether from your TV, receiver, GPU or XBMC.
It sounds like an issue which affects a subset of users: those with systems that suffer from it and users sensitive to it. By all accounts, both here and in professional reviews, the ATI 6450 should be the best clocker out there, and it has many fans here for that reason. That only rules out one part of the puzzle though. Does your NAD support HDMI lip-sync? As another test, bypass the NAD and see how sync is straight to the TV.
