So from what i understand at the end of the day i dont have to add money for a new mobo and i can use gtx 970 on my current one, right?
Right
i just wait for my next salary and its pointless to buy DDR3 right now since ill need DDR4, yes?
That's up to you. It is true that the new board will need DDR4. Can your chip handle a 1080? Yes. I took a good 9 months to save enough money in order to afford some recent upgrades. While I will get a performance increase when I upgrade the board, CPU and RAM in my CPU I chose to get the best GFX card(at $10 under MSRP) and in another year or so I will have saved enough to modernize my build.
is what I have now. The 1080 Ti is too much for a 1080p 60Hz TV but I do have a Vive and it allows me any monitor on the market when I upgrade. Pouring $600+(hoping for an i7) for the board, CPU and RAM wouldn't have increased my performance level to where it is now so I chose to go a little( a lot ) overboard for now until I can balance this thing back out.
