Proud new owner of an EVGA GTX 970 SSC! Replacing the Gigabyte Windforce GTX 670 I have in the sig!
The EVGA GTX 970 card is noticeably shorter and slightly lighter than the Gigabyte GTX 670.
I ran a few benchmarks. The EVGA card is very, very quiet, much quieter at load than the 670 (I can't hear either at idle). I believe the EVGA card must have gotten the promised BIOS update because the fan is not running at idle, and the card sits at 62 degrees C.
I've quickly dialed in +65 GPU, +250 Mem, GPU Temp Target of 80 degrees C, and 110% Power. The core stays locked at 1457mhz, except in a run of Firestrike, in which it seems to throttle down to 1404 because it was hitting the 80 degrees threshold. I still need to play with the fan settings, which I left at default. I can't hear the card at load, but I have a big case.
With these settings, and my 670 OC'ed to 1247mhz, here's the quick comparison (all at max settings, 2560x1440):
Bioshock Benchmark - Avg FPS
670 - 53.23
970 - 76.96 ----- +45%
Firestrike - Combined Score/Combined FPS
670 - 6491/13.62
970 - 9532/21.2 ------- +47%/55%
Heaven (4.0) - Avg FPS
670 - 22.6
970 - 33.2 ----- +47%
Valley (1.0)
670 - 28.3
970 - 35.9 ----- + 26%
So, about a 45% or more boost from the GTX 670, except for Valley, which only boosted 26% (curious...).
I'm pleased so far.
I do wonder if my 2500k is holding it back any.
