Reviews - Gigabyte GeForce GTX 780 WindForce 3X

Can Gigabyte knock EVGA's SuperClocked ACX off its perch?

Obviously a fast card, but this review really highlights just how good EVGA's ACX cooler is...

[Andi-C]

I've got this card & its very quite, even when gaming. The thing with the ACX is thats its £50 more for a lttle extra & when you look at this to the Ref its a good price over the ACX...

definitely puts my ageing 5870 to shame, that's true

5870 was an awesome card. Use to run them on crossfire but don't update unless you have too.

Thanks for the review guys.

Just looking at the EVGA review, how come when you overclocked the Gigabyte GTX 780 Windforce, you didn't overclock it to the same level as you did the EVGA GTX 780 Superclocked ACX?

Gigabyte = 1010MHz vs EVGA = 1037MHz on the GPU overclock.

Here is my Gigabyte GTX 780 WF OC 3GB @ 1215/3713 anyway, multi looped in Heaven 4.0 for stability.

2500k @4.8GHz
ASIC Quality = 74.6%
320.18 drivers
Max Boost = 1215MHz
Memory Clock = 3713MHz
Max Temp = 73 °C
Room Temp = 24.4 °C

hope they will release 5x windforce

What voltage do you have yours set at?

[YazX]

ok wait, are you kidding me here?! Winforce is the best cooling among all other solutions, you measured the noise without setting equal fan curves and complaining about gigabyte is noisy?!

And for this card specifically, you can push it alot more than EVGA due to perfect cooling solution, yah i agree gigabyte didnt push it the way it should be, but you can push it yourself, if you want to test overclocking, then push both of them to the max limit and see who performs better.

Gigabyte is better option and its also cheaper, dont get me wrong, im EVGA owner since 8800GT and still own EVGA SLI setup for 500 series, but to me, Gigabyte wins by far in terms of performance and price.

What voltage do you have yours set at?

Mine is set at stock voltage, I have the option of adding +13, +25, or +38mV

Someone mentioned on the OcUK forums that by increasing the voltage on just stock clocks improves the actual Max Boost, need to test that to.

Doesn't matter what custom cooler you have, the only thing that limits you is the silocon lottery in terms of overclocking, the Gigabyte Windforce, EVGA ACX, or ASUS DirectCU II will all keep the cards at around 70°C

Thanks for the info. My eVGA GTX 780 Hydro Copper hits 1202 boost with 1320 peak. I only used a +78 offset for GPU clock with a +600 for Memory clock. I can't go past +78 even with voltage tweak. So I guess I'll leave it there until I get the second card for SLI. But I am sure that my CPU is also bottlenecks my GPU.
