Seeking Community Advice on Final Build components

[_Garff_]

Hey all, I'm in the long stretch of things with finalizing my future PC build for the end of the month.

Now I know a lot can change from now till then but I would like to put my mind at ease, solely on the grounds, I think I researched this to the point of no return and merely would like the opinion of some seasoned builders.

My question is; Which combination would perform better overall?

6700k + 1080 or 6800k + 1070

To make life easier, I don't really plan on OC'ing and 4K gaming isn't really all that important either. Understandably I could easily buy a RX 480 or 1060, I simply want to invest in a strong GPU. The system will mainly used as Multimedia System ( Music + Video Creation, and will be focusing on gaming and streaming, the PS4 isn't doing it for me anymore )

I know someone is probably going to just suggest a 6800k + 1080, which I would love to do but I'm trying to make sure it doesn't go above my budget $2000 - $2500 CDN.

So any suggestions at all would be very much appreciated.

Also just to humor the masses:

This is currently what I'm trying to work with so this is pretty much a serious & much needed upgrade:

Processor: Intel® Core™ i7 720QM 1.6GHz (2.8 GHz Turbo Mode, 6MB Cache)
Memory: 6GB DDR3 at 1066MHz
GPU: CrossfireX™ 1GB ATI Radeon™ Mobility HD 5870
Hard Drive: 640GB Raid 0 (2x 320GB 7,200RPM HDDs)

The 6700K is actually better for gaming because while it has less cores all of it's cores are faster and very VERY few games use more than two or three cores anyway. so definitively the 6700K and 1080

Just get the 6700K processor for the video card it depends on your monitor resolution and refresh rate. For any 1080p (any refresh rate)and a 1440p with 60 refresh rate then the GTX 1070 would be your best buy. For 1440p with a 144 refresh rate then the GTX 1080.
