I guess i'm trying to figure out which is "bang for the buck" within a 6k budget,do I get Z5 at 970 and still have enough money to upgrade to 500 GB SSD or a D5 which has better vram and a desktop processor or just go for the best GPU with S5.Decision,decision...

Depends on your usage. If I have that budget, I will get Z5 970m and get 500GB SSD. It is better IMO cause I find it quite impossible for a mobile gpu to beat games like Witcher 3 on ultra settings 1080p. Even Desktop GPU struggle to perform well on that settings. It is also the best bang of buck for gtx970m laptop.
VRam wise, you no need to be so concern about it, since you won't be playing on ultra settings, you won't need so much vram tho. (I'm talking about the current demanding game like Witcher 3) Lesser vram also produce lesser heat
I believe you can get some discount since you're spending so much. D5 may not be so mobile as it is quite bulky.
If mobility is not a need for you, just get a desktop.. haha
P.S: Not to be offensive, if you're not doing design work, 4k screen is totally useless for you. Your GPU won't support you on that resolution and it is a 48hz panel. (well of course old game will be no problem, but make sure the game support that resolution)
