Got mine on Friday and its been great so far. Only been playing GTA V but got settings up on high and very high with v sync on and its pretty much stable 60fps, just the occasional drop every now and then.
The card is very cool and quiet, reaches up around 60C during gaming but I adjusted the fan curve so the fan comes on at 50c. The default seems to keep the fan off below 60C which means it keeps stopping and starting which although silent I didn't like the idea, would rather have it running at a low speed during gaming.
But very happy, small, powerful card, doesn't even make the fan spin up on my PSU and the card is really quiet, no coil whine, you can't even tell I added a GPU to my PC without looking.
