I love MSI Afterburner myself, it shows on my g15.
On a side note, let me ask a question: I've been overclocking my GPU (since it is a overclocked edition) but recently it has been dropping back to standard clocks without notice. Both MSI afterburner and Catalyst Control Center are set to 905 mhz but after about 1-2 hours of on-time the card drops to 500 mhz and sticks there. Its getting really annoying since the only thing that works is restarting the computer and the difference between 905 and 500 mhz is about 15-20 fps in WoW. (fyi: a standard 4890 runs on 500mhz, mine should be running standard on 900mhz and i've overclocked him all the way up to 975 mhz in the past (but due to some games not being able to handle that, glitching textures, i stopped doing that)
