Hey guys, I noticed that a lot of people were having crashes on BF3 due to Gigabyte's card and I was one of them. I see posts where people say up the voltage, under clock the card, etc. DO NOT DO IT! JUST RMA THE CARD!!!
I even had my first fail GTX 560 TI OC card replaced with another and I had the same problem (had to under clock to play).
I then sent that back and now have a MSI GTX 560 TI OC and it works perfectly. Don't stress out people it's your GPU!
And Gigabyte's website & support is utterly terrible; not only is the driver download section terrible, if you manage to find the BIOS for your GPU it doesn't even let you flash it!
Bye bye Gigabyte..
