When it comes to innovation in
the computer world, Gigabyte has really stood up to the plate with this
videocard. The GV-3D1 is the first PCI Express videocard on the market that has
two GeForce 6600GT cores on one PCB, and is SLI ready (with compatible
motherboard) right out of the box.
interested in the Gigabyte GV-3D1 you'd better have a big tidy case as the card
is quite long. GeForce 6600GT videocards usually don't run too hot but when you
put two of them together on the same PCB heat is definitely an issue!
this Gigabyte a huge copper plated aluminum heatsink on the front of the
videocard with two 50mm fans. During testing the card still ran quite warm with
the heatsink temperature between 45-50 degrees Celsius during benchmarking. In
any case you'd better have good airflow in your system if you plan to install
While a dual-core SLI
single-slot solution videocard has a lot of potential, since SLI motherboards
are quite expensive, in its current form the Gigabyte GV-3D1 is rather limited.
The problem lies in how the PCI Express bus is split between the two cores;
apparently a compatible motherboard and BIOS is required otherwise the first GPU
ends up getting all sixteen PCI Express lanes while the second GPU gets
this we plugged the GV-3D1 into the Gigabyte GA-K8NXP-9 nForce4 Ultra
motherboard and while the card worked, we could not enable SLI. If Gigabyte
could only engineer in broader motherboard support that would divide the PCI
Express bus properly, the appeal of this type of videocard would be much
failed to overclock the Gigabyte GV-3D1 even slightly in SLI mode, its stock
performance was excellent, and it consistently turned in higher numbers that the
other 6600GT cards in our benchmarks, even when running in single GPU mode. The
faster 1120MHz memory speed of this card probably had a lot to do with these
you who are interested in the Gigabyte GV-3D1 might like to know that at the moment,
the videocard is only sold bundled with the Gigabyte GA-K8NXP-SLI motherboard,
with a retail price of $610 CDN ($499 US) for both. Considering
the price of a regular SLI motherboard and two GeForce 6600GT videocards, users
end up saving around $100 CDN by going this route.
