Would like support on switching or upgrading build

[Lightsity]

I asked this a while back, but would like a fresh set of opinions, and answers
This is my current build, certain parts are not included as per see
https://pcpartpicker.com/list/wQZrJx

With the exceptions of peripherals, power supplies, and hard-drives,
I would like to know would it be efficient to switch to an intel based setup or seek better parts in an AMD based machine. Background information to know would be that I frequently edit videos, and play games. I purposely left out questions on Ram as I have an understanding of where I'll need to move with such. I do plan to stay with my current graphics card as it is both intel and amd supported, therefore placing this question on my "Motherboard, and Processor.

I know i'll need more ram btw

It's very, very basic 2 core processor. Cheapest way to get a lot more performance would be to go to http://www.newegg.com/Product/Product.aspx?Item=N82E16819113408 to tidy you up until next build.

Using a game as an example, Overwatch we'll pick.
I would like a clean, but affordable transition. I guess i'll like to do an upgrade that's efficient all around, so how great of a performance boost do you estimate this will grant.

Edit- I feel the term "Upgrade" after re-reading your reply was taken mainly into answer, however i'm more so asking whats contains more efficiency, upgrading amd based parts, or transitioning to Intel based parts, to then follow up the question of suggested builds, that are cost efficient, for performance

Well that 880K would be a good match for your GPU specially since you don't plan to replace it soon. Otherwise you'd be looking at whole new computer, not only upgrade.

I would assume switching would entitle such, do you have perhaps a way to scale how big of a performance boost? Or are there more efficient processors of close range with different motherboard

+1 CountMike. Not a bad choice for less than $100US. Uses 30 more watts, likely your PSU can handle that, but check.

Alternative is an i3 build on a cheap but solid MB for $200. Or an i5 build for $300.

Your video is nice, EVGA GeForce GTX 960 2GB Video Card, and for 1080P would be fine with all three choices.

You have plenty of memory with 8gb, however using a single dimm gives up a few percent performance. All of the CPU options can use two dimms at the same time doubling the memory bandwidth which helps some applications more than others. Adding a second dimm of the same specs gives you two channel memory. But this is low single digit performance gains for gaming, not near the gain from the CPU / CPU+MB swap. If you do a CPU swap to something that needs DDR4 get a pair of dimms.
