Don't buy the SC, get the Super SC (SSC). The reason is that the SSC and FTW have a better heatsink setup, if you plan on overclocking. For my money, I'd get the EVGA GTX 970 SSC 04G-P4-3975-KR. Please be aware that the 2975 model of the 970 SSC is just as good but has two DVI, one HDMI, and one display port. I prefer the 3975's three display port and one HDMI.
You didn't ask this but another option is the R9 390, if your power supply supports it. And yet another option here in the US is buying an EVGA b-stock (factory refurbished) card. I just checked and there aren't any GTX 970's in stock, but I'm guessing there will be in two weeks or less. No way to know for sure.
