cont’d:
At any rate, that Dell spec is interesting because it would seem to indicate that their specific version with “only” DDR3 can still pop 3840 x 2160 at 60 Hz out of the DisplayPort, though there’s no indication if it can do that simultaneously from all 4 DP’s. (Seems a stretch, but that’s not a deal killer.)
If the cards shipping to me tomorrow are GDDR3 as spec’d*, then I’m in good shape.
Maybe Dell left off the “G”?
Oops, forgot the “*”:
“*Maybe Dell left off the āGā?”
