Will there be a good performance difference between these clock speeds ?

GTX 970.

Models 04G-P4-2972-KR, 04G-P4-2974-KR, and 04G-P4-3975-KR.

3 different performance models. 2 are factory OC'd.

Clock speeds(core, boost, memory):
- 1050, 1178, 7010
- 1165, 1317, 7010
- 1190, 1342, 7010

I am considering getting the second, most highest clocked model. But I might wanna squeeze out extra $$ for the highest clocked card.

I am not asking if the factory OC'd cards will be worth the extra $$ now. I'm asking if there will be a good/fair performance difference between them and the reference-performance card.

Please don't say "just buy the reference speed card and OC it.". Obviously, I will OC later on. I want to know if the F-OC'd cards will actually perform a lot better before/after OC'ing than the reference speed card.

we need more then card clock speeds. some cards overclock better then others. We need actual models to be helpful

well this MSI card has

Core Clock
1140 MHz
Boost Clock
1279 MHz

And this EVGA Card has

Core Clock
1190 MHz
Boost Clock
1342 MHz



And they are both compared here.

so 70mhz more = a few FPS.

Check first post. Updated clock speed info and added model name info for the 3 cards I am looking at.

Hmm tough call. I have personally had bad luck with EVGA cards and overclocking in the past. Frequently i would have to down clock them to get them stable but to be fair the Maxwell is very overclockable so it will likely be less of an issue. On the MSI side i have had trouble with them in the past as far as fans going bad. They have been known to put in crappy fans on their custom cooling solutions. If it were me I would likely choose the EVGA model with the highest clocks.
