Canon 60D @ ISO 5000?

I've always set the ISO limit of my 60D on 3200. I had a chat with a friend who shoots with the 5DII and he mentions that he goes up to ISO 5000 and the results are still very good. So that got me to thinking if my 60D can create pictures with acceptable quality at ISO 5000. Here's what I got:

Canon EOS 60D + Canon EF 85mm F1.8 USM | 1/200 sec, f/1.8, ISO 5000

It's been post processed as per my standard settings although I had to push up the noise reduction more. What do I think? It's alright I guess. There are some obvious noise in the darker areas but I think it will be find printed. 

But I doubt I'll always use it much. There's just something about the image. It feels 'murky' and 'rough' somehow. I think I'll do some other tests under different lighting conditions.
