AMD knows how to make GPUs. They make great cards, and every now and then, nail it and make an absolute perfect card. They succeeded with the 5850 and it's brother 5870 and they succeeded again with the 7970. The 5850 had MASSIVE OC headroom with a starting stock core clock at 725 and people easily reached core clocks of 900 and above the 1 ghz mark. With the 7970, the OC headroom may not be as large, but is still there. A starting core clock of 925 and an easy OC up to 1125/1575 is just a lower oc.I had a 7970 reference card by Sapphire, and I loved it. It did run extremely hot, at around 85 degrees C at 1175/1575. I had to set the fan at around 65% at that temperature and the sound and heat was just too annoying for gaming for more than 10 minutes. I considered buying an aftermarket cooler for around $80 which was reviewed to be excellent, although a tad on the larger side, and extremely tedious to install. I own an Antec 900 case, so combination of putting in another $80 with $579 original 7970 price, amount of work required and the smaller case size put me off buying the cooler. I returned my reference card and switched to this one.The Sapphire Dual-X card is absolutely amazing. Although the GTX 680 is reviewed to be slightly better than the 7970 in a few categories, it is important to remember that the 7970 has a larger advantage in higher resolutions. This isn't to say that the 7970 is bad at 1920 x 1080. The performance of this card is ridiculous even when overclocked to around 1125/1575, which is the max in CCC, and can reach that clock at stock voltage. However, if you would wish to OC it higher, using other programs such as MSI afterburner and Trixx easily suffice.Another amazing feature this card offers is its Dual Bios. It has two bios settings, one for a normal every day use and one suitable for a more aggressive OC profile. For all OCers it is recommended to switch to BIOS 2, which is a simple as flipping a switch on the top of the card when installed but not powered on, and provides so much more comfort in knowing if you brick one BIOS (extremely unlikely) you can just pop to the other one.My main original problem with the reference 7970 was the fact that it was very loud and hot. Running this card at 1200/1600 at 1.3 volts with a modest fan profile that I have only seen running at 55%, the card reaches a maximum of 50 degrees C and idles at around 28 deg C. This is a fantastic improvement, and the fan is nearly silent as well. The only time I hear the fan running over the case fans and operation volume is when I'm torturing the card in Heaven, Kombustor, 3D Mark Vantage, and other benchmarking programs.This card blows the reference design out of the water, but I may have received a card that has random kinks in it. While it is not a dud and can OC a little bit, I am unable to OC it more than 1200/1600 at 1.3 volts compared to other owners of the same card, cpu and mobo that I have talked to. Yes, I know that there are many variables in OCing GPUs but I think 1.3 volts is rather high for a more average clock speed. I have read multiple reviews of people achieving 1200/1600 on voltages around 1.22, and my voltage of 1.3 seems like overkill. Running the card at 1200/1600 is still satisfactory and still deserving of a 5-star rating.Overall, this purchase is absolutely worth every penny. When compared to the GTX 680 at around $500, with performance that rivals if not outperforms the GTX 680, and for a good $30 cheaper, this card is an absolute must buy for computer enthusiasts and gamers alike.
