3DMark is synthetic but a good way to stress a system. The G45 comes in a few hundred below Nvidia's 780a (basically a GeForce 8300) and over a 1000 points lower than the 790GX.

Here we're surprised to see the G45 again do well on a mainstream title at least, even with full HDR the score even tops Nvidia's integrated graphics.

AMD's QuakeLive is basically Quake 3 in a web browser and does a pretty good job of that. The G45 again does well, more than likely do to the much better Q6600 performance against the Phenom but still tops Nvidia with that boost.

UT3 is another game we tested DX10 with and again the scores were some of the chipsets worst.

Surprisingly if we put Company of Heroes all the way to the lowest settings it is fairly playable on the G45.
