Hmmm, I starting to worry about getting my 670 to carry on for another year. It only has 2GB of VRAM (according to the version I can see on Amazon)
I think I can probably hold off for another year to get the 1070, though that's probably still not enough for 4k.
It does give you a reminder of the value that consoles offer. My graphics card alone set me back as much as the PS4 when I bought it
