Answers from an owner to a few questions I've seen in this thread:
Places to buy:
I bought from Newegg, it arrived from CA to NY in 2 days from purchase.
I have heard Amazon is taking ages to ship.
NCIX has them in Canada, no idea on shipping.
Can you brick the card?
You can fail at flashing it, but you can revive the card by several methods
1 - Use another card to revive this one, by flashing again.
2 - Use onboard graphics to revive this one, by flashing again.
3 - Blind flash, writing an autoexec.bat to do the commands you want in a batch file in your USB drive.
This is my first Nvidia card in a long time, but from what I have read and understand about the GTX 4xx series, it runs very hot. This card with stock volts/clocks from the EVGA 470 SC BIOS that I flashed, with the voltage tweak, idles at about 35C @65% Fan, loads at about 60C. This card is rated up to 105C. That leaves a lot of room for more volts, and more clocks.
If any of you have had a Twin Frozr before, you can expect something about the same. The fans are very loud at 100% but they are pretty calm around 55-65%. They keep the card cool at those settings and it pretty much blends in with case and CPU fans at that level.
I have seen this card fluctuate between 260 and 300 shipped at Newegg. I am not sure what they were trying to do but, I bought mine for 260 shipped at Newegg so I think that is a baseline price.
Overall, the flashing process was easy. I am not new to computer so don't expect this to be easy if you are. I am willing to work with people and help walk them through the flashing process, but keep in mind, there are already 2-3 old guides, and 1-2 brand new guides. All you need can be found in one of the unlocking bundles, which will contain the HP Disk Format Utility, Nitbor, Nvflash, and possibly a Bios.
HP Disk Format Utility is used to make your USB boot disk.
Nitbor is a Bios editor that you can use to turn .bin files into .rom
Nvflash is the baseline program that is used for the flashing process.
The 470 Bios is what you need to unlock your card.
Disclaimer: Your card may vary. Flash at your own risk.
Feel free to PM me or respond here with any (intelligent) questions. Make sure to check the threads related to this topic (the owners thread, the unlock guides, etc) before asking me, but I will be happy to help if you can't figure things out.
Good luck folks and enjoy your new card.
