is there a difference between different refrence cards?

[1832vin]

other than the clock difference, why is the price difference?

i have a few quid to spare, and would it make more of a difference of OC? but the refrence 980 is only 6 pin, so power is limited for OC.

and i want the refrence for watercooling

they are not different in any real way some companies spend more to get cards that are guaranteed to clock higher though which in turn costs the consumer more

If power limit is your concern, have a look at Valley Benchmark and 3D Mark threads here... you will see that I can OC my GTX980 SLI under air already up to 1451MHz and this OC runs stable. Oh and the VRAM is OCed by 510MHz.

My cards are in reference design. Sure down the road you will see cards like the EVGA classy with cherry picked chips that might OC better, but I´m sure I can push my cards easy beyond 1500MHz when I´ve got my EK heatsinks for them.

How much of a gain do you notice by oc your cards to that level, that oc seems pretty nice maxwell sure is looking to be like a lot of fun to oc with

The gain is great. I started testing with stock settings and had in Unigine Valley about 4700 points. So the clock speed and RAM speeds scales very nice with the OC whilst noise and heat are no where near become an issue. Ended up with 70° Celsius around and that was with these high OCs, that´s why I decided to keep these high settings as my own standard settings now, because it runs very stable.

Nice mate, just curious what score did you get in Valley with the OC applied compared to stock clocks?

You will find some review and results here in this forum, should be on one of theValley Benchmark thread pages .
