I couldn't agree more, Thunder and it's the exact approach I have.
Even the average FPS is hoax, when using the ingame measurement. In my first run, before that last post, I had an average FPS of 238, because I ran the game without vertical synch. IMHO it's just a digital version of a ruler, if you know what I mean.
If my games run with 30-35 FPS I'm even more happy than with FPS reaching from 200 to 25.
Synthetic benchmarks don't show anything anyway. ATI and nVidia have years of experience to optimize their drivers for these tests, without really having any positive effect on games.
