SimRacing FTW!
I am using Nvidia's Shadowplay to record and/or live stream, works great has barely any performance impact but you have to have an nvidia card obviously. I use am O/C'ed 780 along with a 2500k O/Ced to 4.5Ghz, that chip has proven to be the best value for money I ever bought for my PCs and I still don't see any reason to upgrade it.
