For streaming you need a minimum of a 2600k.
Streaming is hard on your CPU not on your GPU. Your GPU renders the frames you see on your monitor, but your CPU renders the frames for streaming. You must have a powerful processor to stream smoothly.
Your internet is good enough to stream at 1080p, so you should have a processor to support this as well. The higher the resolution and framerate, the more CPU power it will require. I stream in 720p at 25fps with my 3930k at 4.5ghz and my stream alone uses ~20% of my CPU. The 3930k is overkill with 6core, 12 threads, but you get the idea. Stick with the x79 chipset and a 4core CPU if you want to save a bit of money.
Also the recommendation of ASRock board is a good one. At their price points, you'd be hard pressed to find a better board.
