ASUS GeForce GTX 680 Maximum Overclock Graphics Card Review


Starting with the build quality of the ASUS/NVIDIA GeForce GTX 680 we have a reference style card which offers a good, solid level of quality. The card is assembled well with no loose components and quality components used throughout, though we know that there will be custom models released by ASUS soon which offer enhanced levels of build quality which is always a bonus.

The main design of the card, and GPU, will remain the same though and on that front the GTX 680 is hard to fault. We have a card which supports all of the latest features such as PCIe 3.0 and DirectX 11.1 as well as PhysX, Stereoscopic 3D, HDMI 1.4a, DisplayPort 1.2, and even has its own dedicated video encoding accelerator. The ability to power three screen gaming (including 3D, without the need for active adapters) brings it up to the level required for a modern enthusiast GPU and the ability to add a fourth screen ensures we can keep track of the online world while gaming. The ability to enable FXAA in all games is also a bonus and for anyone gaming at 1920×1080 that would be the recommended setting as the card is more than capable of offering the enhanced IQ and playable framerates.

The power design is also hugely impressive and that starts with the power socket layout which keeps wiring compact before moving on to the more technical aspects where the Kepler excels. By taking a leaf out of the features used by modern CPUs NVIDIA have significantly improved on the power use of their previous generation but not only that, they offer better performance in this area than the 7970, running on 50w less power when gaming.

The implementation of hardware monitoring and power/performance balancing doesn’t negatively impact framerates though and at 1920×1080 the reference GTX 680 almost always exceeds the performance of a reference clocked 7970, in fact it tends to match or exceed the 7970 running at its maximum rate for air cooling. At 5760×1080 the result is a little less clear cut though. The GTX 680 still performs well and does win in some benchmarks but generally it offers similar performance to a reference 7970 rather than exceeding that level. That is of course until we apply the ASUS GTX 680s own maximum overclock. Here is a summary of which card Max OC card won each test, based on average framerates:

1920×1080 Winner
Battlefield 3 ASUS/NVIDIA
Shogun 2 Tie
Arkham City N/A (AMD don’t support PhysX)
SW: The Old Republic Tie
Mass Effect 3 ASUS/NVIDIA

5760×1080 Winner
Battlefield 3 Tie
F1 2011 AMD
Shogun 2 AMD
Arkham City N/A (AMD don’t support PhysX)
SW: The Old Republic AMD
Mass Effect 3 ASUS/NVIDIA

Thermal performance is also decent on the ASUS card and we look forward to seeing what they do to improve the load performance with dual slot, dual fan coolers which will no doubt lower noise levels even further… even though the stock fan is actually very quiet.

So that brings us to value where the GTX 680 with an RRP of £429 inc. VAT or €419 exc. VAT sits just below the 7970 level. At the RRP the GTX 680 offers good value for consumers who are looking for an enthusiast product however ASUS seem to be sitting at £439 at the moment and could do with a small price drop.

The GTX 680 offers significant gaming and power enhancements over the last generation of NVIDIA cards and is priced very competitively against the 7970 which it regularly matches or exceeds in gaming. When we overclock both to their limit the GTX 680 provides the best framerates for 1920×1080 gamers, at 5760×1080 the comparison is much closer but no less impressive.
