But why didn't this problem manifest itself when I had only the single gtx 670?

Were you using the same settings for the single GPU that you were for SLI?

Maybe a single 2gb 670 runs out of steam at that resolution for that game maxed out long before VRAM could be issue?

I can't find any 670s listed on evgas site But I'm going to assume that it has 2gigs of memory and most likely
since that memory doesnt stack in sli configuration you gpus are just eating that memory up and not able to
clear fast enough to prerender the next set of frames fast enough when you die and thats why the lockup.

Maybe sli makes a sharing of vram very bad.so now you see why I said you time ago that 2gb vram wasnt enough for 2560x1440 for games newer than 2012 or with demanding graphics

Think ive sorted it now. Its down to the resolution scale. At 100% or more, I get that annoying crash thing, but less than 100% im getting constant 60fps on ultra with AA off.

Resolution implies vram.so you need 4gb gb models or a 3gb card(s)

I will just use these for now until maxwel comes out I think.
