CPU usage can wildly vary from game to game and will be reduced at higher resolutions! Not uncommon to see GPU usage at 99% and CPU usage at 40% on A 3930K, 3770k, etc!
GPU usage at 1920 x 1080 resolution in a game such as Metro 2033 should most always be at 99% - 100% if the CPU is correctly feeding it instructions! If it is at, say, 70%, it is being bottleneck by the CPU! CPU usage will be at 100% during this period!
A 5 - 7% bottleneck refers to the GPU does not go above 93 - 95% usage in demanding games. In this scenario, the CPU will be maxxed out at 100%
Hope this helps!

This is mostly correct, but id like to point out one thing. More then likely it will be 1 or 2 cores that will be maxed out, rather then whole cpu, unless of course it's a single/dual core.... In most scenarios games are only 1-2 threaded. There are some that go higher, but the highest threaded game i know of is BF3 which uses 6, and i can't think of another that uses 6. This is why for gaming Intel is so often recommended, especially the i3 for budget builds, because their core performance is so strong, as well as far as i know, most games use 2 threads. The 4 module FX cpu's can keep up with a 2500k, but that's only when 8 threads are used, no games are 8 threaded.
