Summary: I'm using two of these in SLI with an Intel Z87 motherboard. No issues whatsoever in any benchmark or game I have tried thus far. Skyrim runs beautifully. No driver or SLI issues at all. Better than a single GTX 780 in most applications.
Summary: First off, I bought this card to replace an HD 5770 which just wasn't cutting it running new games on max settings with playable fps. I had to go with this card instead of an R9 280x because just before I bought it, my motherboard failed and I had some budget problems.
