Which Graphics card Vendor are best for OCing?

The Nvidia Kepler arhcitecture has the voltage locked on their GPUs though I think MSI has some brands that can Overvolt and get better performance. I am aware it really depends on the GPU you get and how well it can OC. My Reference based GTX 680 is a very poor overclocker but the temps are really low It is like their is enough power being constrained to hamper it's performance. I think the MSI lightning are typically designed for Overclocking...Which other's are well known??

They vary from GPU to GPU. For GTX680 I'd like Asus as on many other cards. But many reviews of GTX 670 say Gigabyte is a better all rounder.
A lot of guys like MSI because they had high factory overclocks. Now EVGA seems to be king - for 7 series.

For AMD, a lot of people say that Sapphire is better than Asus.

But not many people like Gainward, Powercolor, Palit, Galaxy.

They're all the same. They're all the same GPU and PCB and components they just design and put new coolers on them only Asus and EVGA have changed components for they're own personal flagships. You can get the same performance across all same class GPUs. Its the cooler that has to keep up so Asus dcuii and windforce editions have great cooling so they're more capable overclockers.
 


only partially true and it depends on the model cards.

No it's really true. The GPU and PCB are made by the same company and then dispensed too the 3rd party corps for they're coolers EVGA and Asus design and have new PCBs designed for different purposes but the GPU is the same.... The only difference is the cooler and is capability to keep up with heat dissipation. Take any one of those GPUs put a water block out and it'll blow all the others away.... So I think I'm right.

Yours and my GPUs are prime examples of this the reason our GPUs exist is for over clocking we have a ln2 bios for literally giving us the GPU to run with now which of ours would win at performance the one that could be over clocked the highest if I had a water block it would be mine cause I could go faster than the air cooled. So in essence the GPU with the best cooler is the best of card. Oh and I forgot MSI makes short versions of PCBs so add them to the pool.
 
depending on the model lots of companies "customize" the pcb, thats why there are so many listings for difference blocks on the same gpu from ekwb. now how far are they going to "customize" the pcb, not sure. usually the highly customized pcb's are only made for the flagship gpus and are only made for the amount of "binned" gpu die's that each company has access to. evga gets first pick from nvidia every time though. msi does get a good handful as well. gigabyte doesn't really play the world overclock record thingy, haven't seen asus do it either. but i know sapphire does get up there from time to time for amd but im not sure which models they are doing it with, i think their toxic line. usually is evga for nvidia and msi for amd, though msi trys hard with their nvidia lightnings.

That's not my point. There higher binned chips will of course perform maybe 10-15% better but if the cooler and the acx let's face it isn't great won't be able to hold an oc very well without running super hot. Now gigabyte has the windforve and they cool really well you could oc that past the EVGA. Or Asus dcuii has awesome cooling and could go past both of them really but take even the lowest quality GPU off the lowest selling vendor and put a great cooler on it it could easily win. Thus my point its the cooler not the company. Different PCB different this or that is irrelevant when in regards to a GPU they do not alter. Performance wise yes you get better fps out of higher quality parts plus a good oc but that's not what was asked.
 
gotcha.... yes, especially for gk110s, most would need some form of water cooling to max out.

though evga gets most of the binned chips that get a higher clocks at a lower voltage, on top of the fact that the chip can actually handle the higher voltage. some chips are high clock low voltage, but hit an internal limit that wont allow any higher clock even when adding more and more voltage, ie: wont handle higher voltages no matter what cooling is used. classifieds gk110's like ours "should" keep scaling with the voltage and core clock and keep that scaling at much higher voltages as well which in turn equals out to more core speed as long as you can wick away that darn heat.
