I'm currently using a late 2011 21.5" i5 imac for gaming/editing and such with no problems Up until recently have I been thinking about building myself an actual gaming computer. I'm either going with A. 4820k with x79 sabertooth and a gtx770 or B. 4770k with z87 sabertooth and a gtx770. The MAIN use for this computer will be streaming everytime I game. Some video editing and some photo editing. What It really comes down to is what option is better for full time streaming while gaming
