Final thoughts

The capability rating compares each graphics card with GeForce GT 430, which is considered a baseline, or 100%. The rating is based on both synthetic and gaming results and shows, as the name implies, what a product is capable of.

The usability rating is obtained by dividing each card's capability rating by its price. It basically shows whether a given product is over or underpriced, considering what it can do, and thus how reasonable it is to buy it.

The complete ratings can be found in our i3Dspeed. Below are just the parts relevant to today's review.

Sorted by capability (high to low)

# Card Capability rating Usability rating Approx. price, USD
04 GTX 680 2048MB, o/c to 10901190/6300 760 120 631
05 GTX 670 2048MB, o/c to 11601260/6200 730 139 524
06 HD 7970 3072MB, o/c to 1100/1100/5800 720 123 585
07 GTX 680 2048MB, 10001100/6000 720 114 631
08 GTX 670 2048MB, 9151030/6000 680 130 524
09 HD 7970 3072MB, 925/925/5500 640 109 585

Everything is clear and predictable here: the overclocked GeForce GTX 680 is the leader, also on a par with our three graphics cards.

Sorted by usability (high to low)

# Card Usability rating Capability rating Approx. price, USD
23 GTX 670 2048MB, o/c to 11601260/6200 139 730 524
24 GTX 670 2048MB, 9151030/6000 130 680 524
26 HD 7970 3072MB, o/c to 1100/1100/5800 123 720 585
28 GTX 680 2048MB, o/c to 10901190/6300 120 760 631
30 GTX 680 2048MB, 10001100/6000 114 720 631
32 HD 7970 3072MB, 925/925/5500 109 640 585

Though GeForce GTX 680 is more expensive than Radeon HD 7970, its significant advantage in performance and functionality lets it score a higher capability rating. The overclocked HD 7970 (which is supposed to give you an idea about the performance of Radeon HD 7970 GHz Edition) has a higher rating than GeForce GTX 680 only because we assumed it should be priced the same as a regular Radeon HD 7970. Our August 3Digest will have more precise results.

ASUS GeForce GTX 680 DirectCu II TOP is a fine version of GeForce GTX 680. It comes with factory overclocking but can be pushed even further by adjusting clock rates and core/memory voltages in the ASUS utility. The cooler is quite big but produces little noise.

Gainward GeForce GTX 680 Phantom is a nice factory overclocked card. The only disadvantage is its noisy albeit great looking cooler.

Zotac GeForce GTX 680 AMP! Edition is an excellent solution with the most effective cooling system of all three. Factory overclocked, too. However, reference supplementary power connectors (two 6-pin) may prevent it from becoming an overclocker's choice.
