Doom 3
IGP sucks for Doom 3.
But at least it is very playable on this board at 640x480 - rare for an IGP solution.
Add a decent card, and you will get very good scores with the Asus Crosshair II Formula.

Quake 4
Quake 4 did not do as well with the Asus Crosshair II Formula, and while IGP scores were still playable at 640x480, it did not reach 60fps.
