My GTX Titan is dying :(

Hi All,

The GTX Titan I got second hand from someone on here has started to show artifacts and then crash my system when gaming

So I'm looking for a replacement,

options:

1080ti
1080
1070ti
1070

I game on a single HD monitor, so not too demanding there, but I will be getting an HTC Vive Pro in the next 12 months.

So 1080ti now and keep it when i go VR, or something lesser and upgrade again when I get the VR system.

also, why are the 1070ti prices same / higher than 1080? I confused!!!

Thanks as always R.
