Creative Labs Annihilator Pro Review
Overclocking
Using Entech's Powerstrip utility, I was able to overclock both the Annihilator Pro's core and memory speeds. With the GeForce SDR, I reached core and memory speeds of 150MHz/200MHz and have been running at 140MHz/190MHz since I've had it.
The Annihilator Pro seems to offer a similar level of overclockability as I was able to reach 145MHz/345MHz, up from the default speeds of 120MHz/300MHz, and could possibly have gone higher. To test the stability of the Annihilator Pro while overclocked, I ran Quake 3 in a continuous loop for over 2 hours.
The following table shows the gain in frames per second while I was determining how high the Annihilator Pro could be overclocked. The results are from the Quake 3 demo001 running at 1024x768 in 32-bit color using high quality settings:

Incredible! I was finally able to reach the magical 60 fps in 32-bit color on my little old Pentium 2-450MHz. Time to break out that can of whup ass :)
These are the overclocked results of 145MHz/345MHz compared to the default clock speed results of 120MHz/300MHz. Again, all results are based on high quality settings in 32-bit color:
