I bought mine to heat my apartment.
LOL!
Mine does that too! Especially if Maya is pooping out a render.
I actually bought mine for expandability (I lied, I never played farmville

) and speed.
I use, on a daily basis:
- Maya (omg renders are sooo fast!)
- ZBrush (this runs so fast too!!! HD modeling is awesome)
- Corel Painter (No more turning off brush ghosting!)
- Unity 3D (always runs well but still decently faster then on my lappy)
- XCode
- Aperture (WOW this runs much faster then on my laptop)
- Logic (I don't delve too deep into this one but so I don't notice a speed difference but I'm sure I would if I did more with it. My needs are basic with this guy)
-Photoshop
I've had it since monday but haven't got to really start setting it up until wed, then I got my wisdom teeth pulled thurs so I was out most of thurs, and by this morning (sunday) I finally got all of my programs reinstalled, all of my ram/hard drives installed, all of my backups finished (those take a looong time) and now the only thing missing are dual 27 inchers. Once those are available my setup will be complete
This thing is fast. I've ripped my few movies that I have left that haven't been destroyed and ripping is so fast and encoding is ridiculously fast (using handbrake) and I don't even have the 64 bit version. (I can't find it and 64 bit vlc

)
Anyway I absolutely love the thing and recommend it to anyone.
Well, enough playing around. I have a TON of 3d work to get done now that its up and running

(Well, I shouldn't say work, I'm a student so a ton of hobby to get done

)
