Does type of GTX 780 matter for watercooled overclocking?

post #1 of 4
Thread Starter 
Per title, I've tried to read up a lot but have not found an answer for this. In Australia I've access to these cards:

  1. Palit GeForce GTX 780 3GB
  2. ASUS GeForce GTX 780 3GB
  3. ASUS GeForce GTX 780 DirectCU II OC 3GB
  4. EVGA GeForce GTX 780 3GB
  5. EVGA GeForce GTX 780 Superclocked 3GB
  6. Gainward GeForce GTX 780 Phantom GLH 3GB
  7. Gigabyte GeForce GTX 780 3GB
  8. Gigabyte GeForce GTX 780 OC 3GB
  9. MSI GeForce GTX 780 3GB
  10. MSI GeForce GTX780 Gaming Edition 3GB


With the exception of Gainward, it at least appears to me like they are all reference design with different "cooling" options.
If I'll be stripping out the cooling for a waterblock, should I just go for the cheapest card (palit)?

Prices do vary, it's from $749 (Palit) upto $899 (Asus o/c).

I want to get best possible OC results under water from one of the cards above.

Hard to say whether it's worthwhile to go for the cheapest since it hasn't truly been confirmed whether the chips used for the OC's variants are higher binned or not. It would sound reasonable the OC editions would possibly have better potential but I would say you're really faced with luck of the draw.

To close off my own thread. More expensive does not mean better.

I bought GIGABYTE GTX 780 reference with 3 years warranty. It was only $30 more than the cheapest one which had 2 years warranty.
It overclocks like a beast (under water) and it is supported by this forum fantastically because most people have reference so: bios, clock advice, water block availability - all in favour of reference.

Recommend reference with 3yrs warranty.

EVGA allows you to replace the cooling (add water block for example?) and still keep the warranty.
Also, going for reference design makes it easier to find block although some non-reference cards could be better for overclocking - Asus DC2 and EVGA Classified for example have more power phases which should help with overclocking.
Since EVGA classified isn't on your list, I'd go with a Asus DCU2. Think EKWB has a block for it.
