So should i cop any 1080 or are there higher spec ones then others?
Well, I'm not the best person to talk to honestly. I go hard with tech. I have 2 Titan X Pascals (12gb of vram each).
Personally, I'd get a Titan X P. One card plays almost all games in 4K all ultra 60fps. (I got 2 to play in 5K and above)
Or...you could wait for the (possible) 1080ti that hasn't been announced yet.
I'd personally drop $1200 on the Titan X P, but that's just me. It's got the vram, the teraflops, etc., and $1200 isn't a big cost for me. Depending on your needs that might be overkill or too expensive. It all depends if you want 4K, all ultra, or can deal with lower settings. I'm an all ultra guy, so I buy the best possible cards out. That's just me. You may be fine at 4K, medium, 60fps. If so, get the 1080.
