    How big of a jump is the difference between the 13" 2012 MacBook Pro vs the new 15" MBP with the dDGU? We use our Mac right now for a lot of live streaming and video editing. Our current one is the i7 with the SSD.

    You'd be going from a dual core with iGPU to a quad core with dGPU, so the performance bump will be substantial. Video editing applications can be resource intensive and utilize GPU acceleration as well as multiple cores effectively, that is where you'll notice the difference. Video streaming shouldn't really require a quad core.

    Also, the 15" has 16GB RAM default now, so there's a good chance you'll be seeing benefits from added RAM depending on how much you have in your 13" (not to mention if you use the dGPU, you'll free up system RAM reserved by the iGPU).

    Thanks! The program we use right now is running my system at 80% CPU. And that isd where it really starts to struggle and degrade our stream. I am hoping the new 15" will bring down my CPU usage to around 40%. Has anyone ever heard of Wirecast?

    It should be quite a noticeable difference. Screen space, quad core, and specifically the dedicated graphics.

    80% is not even half the CPU capacity of a dual core machine(100% per core is available if your software is multicore compatable), so it seems unlikely that is your bottleneck, I would take a look at your internet upload bandwidth before anything else.

    That is the CPU percentage the software shows, activity monitor shows its running the system dry of CPU power. Don't remember the number off the top of my head. Upload bandwidth is 100mpbs.

    and the software will show 200% to 400% if pushed all the way at least most will, but don't let me get in the way of buying a new computer
