I have a late 2009 27" iMac and it's been a great machine. However, I just ordered a gaming PC and want to use the iMac's display with it. I read during a search that the 2009 27" iMac can be used as an external display using it's minidisplay port.

My gaming PC has the Nvidia GTX 660 and I believe it has DVI, HDMI, and Minidisplay outputs. So my question is this: if I want to use the 27" iMac's display with it, should I use a minidisplay to minidisplay cable, or would it be better to use an HDMI to Minidisplay?

I assume my iMac will also need to be booted into OSX for it to work as an external display, or can you just use the iMac as an external display without booting the machine?

Please advise. Thanks!
