Gigabyte NX88T512HP 8800GT

I recently purchased a Gigabyte NX88T512HP 8800GT. I decided on this card as it shipped with a custom cooler installed, saving me the job of having to do this myself.
I didn't realise it at the time, but this card is also factory overclocked. In fact it is factory very overclocked. The stock speed for the core is 600MHz; this card is clocked at 700MHz. That's a very ambitious overclock, and indeed the largest factory setting I found after a quick glance around the web.
After I installed the card the screen would go dark at random intervals, sometimes at boot, sometimes after several hours, and sometimes during a game. Also the card would display the classic 3D freeze during a game, a sure sign that the card is being pushed too far. By the randomness of the blackouts, my guess was that the card (possibly the memory) was damaged, so I returned the card the next day.
I then waited a week until a replacement card was sent from Gigabyte. But this card too displayed the 3D freeze, something I had seen many times from my past youthful attempts at overclocking.
I was upset at this point. I did not want to wait yet another week for a third and possibly crappy card. I decided to return the card to its stock clocks. I used NiBiTor to capture and create a new BIOS, setting the clocks to their stock speeds of 600, 1500, 900 (1800). I then used nVFlash.exe running from a startup floppy to reflash the BIOS of the video card. So far a week on and all is well.
This is my first experience with a factory overclocked card—and it sucked. Please don't anybody buy this card.
