nVidia GTX680 Review
A quick glance and one would think this was a standard reference design card, and of course in a lot of ways it is. However some subtle design tweaks have meant that all isn't what it seems.
On the right we have, from top to bottom, a GTX570, the GTX680 and a GTX560. As you can see the GTX680 isn't a behemoth, but rather a reasonably sized card.
One of the most obvious changes is the redesign of the power inputs. Instead of side-by-side they are now stacked which allows for better internal placement of the fan and suchlike, as well as a reduction in card size as we saw above.
The business end is much the same as always with two DVIs, a HDMI and a DisplayPort. However it's worth noticing that the GTX680 supports triple-screen 3D from a single card, a vast improvement on earlier cards if 3D is your bag.
Externally at least it looks fairly standard besides the adjustment of the power connector placement. The usual SLI fingers and branding dominate the visible part, as well as the dark PCB.
Beneath the shroud a lot has changed. The heatsink is a complete redesign with the new fin arrangement allowing for greater airflow and hiding some hefty heatpipes. The fan itself contains some acoustic dampening material that should hopefully reduce the whine that smaller fans give and are the primary cause of noise pollution.
