Pretty simple actually :)

My current setup is:

24" main monitor,
22" "support" monitor on my desktop
1080p projector in the living room (10m hdmi cable)

Can i run all of this of the 5870 at once, or do i have to swicth like i do atm with my gtx 8800?

Can't seem to find any clear answer, everybody is just talking about eyefinity and how great that is, but for my setup its not the solution im looking for.

You'll be fine, enjoy the upgrade. :) (EyeFinity is a feature, not a requirement. Same way new-version DirectX hardware ADDS functionality to what it did before, it doesn't discontinue the old stuff.)
 
so the hdmi and one of the 2 DVI is a shared connector?
Geuss i have to ge an active DP->DVI/hdmi converter for this to work, or?

Yes, the HDMI port shares an output with one of the DVI ports.

You will need a DP > DVI adapter.
 
What about using one DVI, the hdmi, and can then a passive DP->Hdmi conter be used?
 
From what I've read, passive adaptors will not work as the signals are not compatible. Which almost begs the question... What good are the passive adaptors for if they don't work?
 
To be clear, you can only have TWO DVI/HDMI displays enabled at any time using any combination of DVI/HDMI/DP ports. You need to use a native displayport monitor or an ACTIVE displayport adapter to get a 3rd display. (a passive adapter counts against the two dvi/hdmi display limit)
 
If you don't want to bother with a display port adapter, you can plug the projector in with HDMI and just switch between the projector and the other two displays in software. I am pretty sure this should be scriptable with the catalyst drivers.

They're fairly pointless on the current 5xxx cards because the cards only have 2 DVI/HDMI clocks; they have their place elsewhere though. The first was on DP only macs/macbooks because they had a clock available to drive a DVI signal. They'll also be relevant on the upcoming again on the upcoming 6x miniDP 58xx card which will be able to use 2 of them to connect to DVI monitors. (Odds are the cards will be bundled with 2 of these.)

Has there been any word on what stopped ATI from having more than 2 DVI clocks?

If you do any degrees related to computer systems or electrical you will find out that trying to have multiple high speed signals running around can be tricky business, if you don't want them to interfere/be interfered by others in a small space. Especially on a chip. There's a reason most processors have an external circuit supply the clock instead of building one into the chip (AVR series micros for example).
