To run the top current games (GTA V, Watch Dogs, The Witcher 3 etc) on a single card maxed out @2160p you are going to have to wait for big Volta in 2018. Pascal next year won't be anywhere fast enough.
Waiting is a terrible option as you will never get to do anything.
Remember in 2018 when you can play todays top games maxed on big Volta there will be games around that will push the bar far higher.
I need to save, that's the main reason its next year as I don't buy things I want on a credit card just so I can have the latest kit, plus there's no rush as I'm happy with my PC at the moment

That's fine I can't justify £1500 on a monitor and graphics card to barely make use of the monitor I'm not an early adopter for that reason, I'll get a new gpu and 4k screen next year when the gpus have the grunt for a steady 60 plus fps in 4k until then I'm staying at 1080p, ultra settings and 8x aa at over 60fps

My 980TI and Samsung 4k cost just over £1000.
Not far off a Titan X ?
