I'll attach my dxdiag so you guys can check out what I have.
I just put in a new MoBo, a Z97 Gaming 7. New Processor, i7 4790k, New GPU Geforce GTX 970. I did this mainly so I could try streaming league of legends efficiently. However, even my in game FPS isn't stable when I am not attempting to stream. It seems like the computer doesn't perform well when I try to use two monitors. When I do try to stream (using Xsplit) my game FPS is horrible, the stream quality is horrible. Overall things aren't as they should be fore the level of hardware I just spent a lot of money on.
This info may not be specific enough, but let me know what you guys think.
