I would suggest that you go with ASUS or EVGA 470s. I have two Gigabyte 470s under water and I can't get them stable above 800 mhz. Probably due to one of my 470s being a bit of a lemon. My temps at 800mhz don't exceed 60C, yet my pc locks up after a few minutes of gaming above 800 mhz. I've also read that the reference gigabytes aren't that great when it comes to overclocking. So as I stated in my first sentence, go with ASUS or EVGA.....imo.
