Now i have seen some posts on the internet about this, but i still want a solid answer, is it really possible to use the imac 27" from 09' / 10' as a display for PC and if yes is it compatible with all video cards ?
im planing to do this with a HD 7970 from sapphire
this is going to cost me some money if it wont work plus i will have to buy an extra monitor if this wont work.

I think it's been explained quite thoroughly on Apple Support Page you mentioned, no need to be another Mac;

To use an iMac (27-inch, Mid 2010) or iMac (27-inch, Late 2009) in Target Display mode with another computer as the source:

  1. Make sure both computers are turned on and awake.
  2. Connect a male-to-male Mini DisplayPort cable to the Mini DisplayPort on each computer. The 27-inch iMac will enter Target Display mode and display content from the source computer.
  3. Note: If you are connecting two 27-inch iMacs, connect a Mini DisplayPort cable to each computer and press Command + F2 on the 27-inch iMac keyboard that you will use as an external display.
  4. To leave Target Display mode, press Command + F2 on the keyboard of the 27-inch iMac that is in Target Display mode. To return to Target Display mode, press Command + F2 again.
One little note on PC side though:

To use these iMacs as an external Windows display:

  1. Connect your Windows capable Macintosh as described above.
  2. Restart in Boot Camp.
You need to be in Boot Camp if your another computer is a PC

If it's a PC, why would you be using Boot Camp? That is just to say if you want to use Windows from a Mac using that connection method.

If you have a late '09 or mid '10 iMac it can take mini DisplayPort input. So you just need to check if your PC has a mini DisplayPort connection and it should work fine.

'11 iMacs can only do ThunderBolt so that means only Macs can use the most recent iMacs as external display :(

Search around here using info for your particular graphics card (on the PC); some have had success, some not so much.

FYI I am using an i7 iMac 27" mid-2010 as a DisplayPort monitor via TDM, being driven by a homemade pc with some 7770 GFX card. Consequently, I can't use the Cmd-F2 combination to switch between machines, which I understand needs the TDM client to be a Mac.
