Both the non-SC version and SC version are in-stock at Newegg.
Non-SC and
SC.
There isn't a huge performance difference between them. Nothing to warrant a $30 increase, anyway.
If there wasn't a noticeable difference in performance then the card wouldn't even be on the market. The price difference reflects the performance difference. The SC is guaranteed to run at its higher factory clock speed whereas the non-SC version isn't guaranteed to run at clock speeds higher than its stock clock speeds.
There is a ~4 FPS difference between the reference 970 and the EVGA SC 970, and they have an even higher clock difference than the non-SC and the SC. So is there a difference, yes, but probably about two FPS. Not worth the additional $30 IMO.
The SC isn't guaranteed to run higher than it's stock clocks, either, no card is. It's very unlikely you won't be able to overclock the non-SC version or the SC version though, if you can't you likely just have a poor chip.
EVGA guarantees that the EVGA GeForce GTX 980 Superclocked [04G-P4-2982-KR] will run at 1241MHz Base Clock and 1342MHz Boost Clock. Any clock speeds higher than these are not guaranteed to work.
EVGA guarantees that the EVGA GeForce GTX 980 [04G-P4-2980-KR] will run at 1126MHz Base Clock and 1216MHz Boost Clock. Any clock speeds higher than these are not guaranteed to work.
You can RMA the card if it isn't able to operate at its factory shipped clock speeds but you can't RMA it if it is unable to successfully overclock.
The The EVGA GTX 980 SC ACX 2.0 [04G-P4-2983-KR] has a 12% performance advantage over the NVIDIA Reference clocked GeForce GTX 980 card @ 1080p display resolution. As long as you're not paying over 12% more for the SC version over the NVIDIA reference clocked version then you're getting the extra performance that you paid for.
