At first glance,
the Abit Siluro FX 5900 OTES looks like a menacing beast.
This card has one of, if not the largest, coolers we have
ever seen on a video card. The OTES, or Outside
Thermal Exhaust System, is comprised of a large, aluminum
heatsink with a fan and duct system that blows hot air out
of the rear of system. There is also a small heatsink
mounted on the back of the card that should further cool the
GPU. The fan mounted in the center of the cooling
system is equipped with blue LEDs that make the whole duct
system glow. Most case modders will definitely be pleased by
the Siluro's appearance. Overall though, the plastic
used for the duct has a flimsy feel to it. The duct
itself if made up of 5 individual pieces that are linked
together. The whole system slides and flops around a
bit. This card also blocks PCI slots 1 and 2, which
may turn off some potential buyers. Underneath the
fancy cooling system, the Siluro FX 5900 OTES PCB adheres to
NVIDIA's reference design.

We snapped off a
few screenshots with the cards, to demonstrate how well
NVIDIA's Intellisample AA engine cleans up jaggies when
enabled. We used both cards for over a week and found
no differences in image quality between the two. As
you can see, with each successive level of AA, the jaggies
are less and less noticeable. The effect is especially
evident on the turret and plane wings off in the distance.
We did notice an anomaly when using any AA level above 4X.
Pay special attention to the smoke in the sky. With
4XS, 6XS and 8X anti-aliasing enabled, the smoke is altered.
We suspect the sampling pattern used and filtering applied
to the image when using these modes is the culprit.
It's time for Some Benchmarks! |
