We don't recommend old builds to users. Even though 3.5-367 may run "better" for some systems, it has a number of issues that 4.0 and above fixes. Everyone's free to use what they want, but we don't tell users to use outdated builds, at least not without telling people that we do not support anything older than 4.0.
Also, you've linked to the old, unofficial site (I'll edit that in a minute). Our new site is http://dolphin-emu.org and the new downloads page is http://dolphin-emu.org/download
