Not sure if anyone has tried the PNY GTX 680 2GB, so here goes...
132% power target
Ran Heaven benchmark...
I didn't try to hit the max overclock cause I just got it, and the stock cooler can get a bit loud for my taste. Although I did try once, driver failure hit at +130 core, so I just reverted back to +125. Will try overclocking more when I decide to exchange the stock cooler for something like the twin turbo II or icy vision rev.2. Will not try water cooling because I have an Alienware Aurora case (that I now despise despite it looking pretty with all the lights and all, I would rather have a more mod-friendly case with more space. I'd have to tear this thing all sorts of apart to make it water cooler friendly.
Overall very pleased, unfortunately I do own a PNY GTX 670 in another build that could overclock a bit better, reaching stock 680 specs in terms of memory and core clocks, but I did switch the stock cooler on the 670 because it had terrible coil whine.
