You might get a performance increase in some games, depending on how they work. I can't explain the technical details of that. From the AMD site:
"The AMD Dual-Core Optimizer can help improve some PC gaming video performance by compensating for those applications that bypass the Windows API for timing by directly using the RDTSC (Read Time Stamp Counter) instruction. Applications that rely on RDTSC do not benefit from the logic in the operating system to properly account for the affect of power management mechanisms on the rate at which a processor core's Time Stamp Counter (TSC) is incremented. The AMD Dual-Core Optimizer helps to correct the resulting video performance effects or other incorrect timing effects that these applications may experience on dual-core processor systems, by periodically adjusting the core time-stamp-counters, so that they are synchronized."
The Dual Core Optimizer certainly isn't going to hurt anything.
I have run into a few games that actually recomend that you install the optimizer when you install the game, so in that case it might make a small difference in performance, for just every day use I didnt see any difference in the performance

It won't hurt anything and basically what they're saying is that the timing for clocking information might be out of sync due to dual cores and cause problems. For example; before I installed the optimizer some older games would run in super-slow motion or in super-fast motion. After the installation, everything ran just fine.
You won't see speed improvements (you're not going to be running Game A at 35fps and after installing the optimizer be running that same Game A any faster; you'll still just be getting your normal 35fps), just the stability of how some games (and maybe some applications) run (see my example above).
