Hmm. So a quick comparison of specs shows I have 3540M transistors, you have 1870M, I have 192 shaders, you have 640. You have 18.8 Gpixel fill rate, I have 20.8, my bandwidth is 90.7GB/s, yours is 86.4. My default clock is 790MHz, yours is 1176, and my memory is 940MHZ default, yours is 1350. Of course, my die size is 294mm2, yours is 148, so less than half the die size, and your release date is about a year newer than mine.

I think it's possible as mentioned above that this was one that had a heckuva lot of bad transistors on it, so they made it into whatever they could, and here is what we ended up with. No idea why the shaders are so whacked, and the bus width is a bummer too, compared to the 'real' 770, but it is a set up from yours. Overall, I think I nailed it pretty good: Frankenstein. Not sure about the Cuda cores, are those the shaders? Thanks for posting that as a comparison, just shows to go you what I've got here.

Keep in mind that they can edit the info stored on the card. The BIOS chip of the card. So while some info on the card can not be tempered with and GPU-z reports it faithfully, the other info can be changed by the seller.

Yeah, I'd agree with that, I have a Zotac Infinity 580 card, that thinks it's an EVGA LC 580 SC, I changed the firmware from the Zotac firmware to EVGA, no harm done, the card actually works better with the EVGA firmware, instead of the Zotac firmware.
