It is perhaps a little presumptuous of me, but here is my monk wrecking Inferno - Act III.
This is after the attack speed nerf. Be sure to watch it in HD.
A bit of background for those unfamiliar with Infero: Act III / Act IV share the same difficulty (and same loot), but Act III is preferred before the elite packs are denser, allowing for more action. Some of the elite packs in this video are considered harder that Inferno Diablo himself. I have not included boss fights because they are "easy" and boring by comparison, but will upon request.
(I'm not sure how to post a proper link on these forums, so you'll have to copy and paste. Sorry.)
Here are the fights (all in real-time, and all start-to-finish):
