hey guys!

I've been trying to find a definite answer but i am finding mixed answers on the internet so i was hoping someone here can help answer or at least shed some light onto my question.

i have a late 2013 27" iMac, i have limited work area, I'm a semi professional music producer and i use Logic so naturally for years i have used Macs, i also do some casual gaming so the GTX 780m in the new iMac was a god send as i was able to work and game on the same machine via Bootcamp, however although the 780m is very beasty its getting to the point where this isn't powerful enough to run games at max settings at 1440p and 1080p looks awful on such an amazing display, i am in the middle of slowly building a gaming rig and was looking into a way of using my iMacs display for the PC, Target Display Mode seems to be the answer, but I'm not 100% certain as i said, I'm getting mixed answers, i am aware that mini display port and thunderbolt use the same plug connection, my question is, if i get a graphics card with a mini display port will i be able to plug that into my iMac via thunderbolt and then use target display mode to display my PC on my iMacs screen?

Using Target Display mode via thunderbolt is possible, however, I'm not sure that would work from a PC gaming rig, even one like Alienware which provides many different outputs. Maybe someone else who is more familiar with what you're trying to do will chime in with a better answer.
