@Freezanator, @Matias_Chambers, how does this look?:

So just to recap, this CPU/Cooler/GPU/Mobo should be a lot better to handle 4k Gaming and 1080p-Vid Rendering, correct?
Thank you guys for the help, I really do appreciate it, I just thought the i5 would handle it easily but hopefully the i7 should do better.
I did just remember one question which I forgot to originally include. If I game on the middle monitor and have say... Google chrome or whatever open on my left and right monitors, I should be fine and not experience any extra issues, right? If so, then thank you again for the help! Sorry it dragged on a bit but, hopefully all should be sorted when I change the CPU from the i5-6500 to the i7-6700 (Non-K) .
