BFG GeForce 6800 GT Overclocked

1 thumbs up

When NVIDIA updates their product line, the GPUs usually arrive in the form of a value, midstream, and high-end variety, thus catering to all budgets or tastes.  Monetarily speaking, it works out for the most part with those in need of a simple upgrade able to get something on the cheap, while Uber-users can get a new card to brag to their friends about, both performance and price-wise.  It's been like this for quite a while, at least since the days of the GeForce 4 Ti4600/4400/4200.

In this year's offerings from NVIDIA, there are three cards, the GeForce 6800, 6800 GT, and 6800 Ultra (and even a fourth if you count the 6800 Ultra Extreme).  They're all based on the same relative architecture, the NV40, and anyone of these cards is sure to give your system a large boost in performance.  Major differences between the current GeForce 6 series of cards include the 12 pipelines on the standard GeForce 6800, instead of the 16 found on the other cards, and speed increases for the GPU and RAM for each subsequent version.  Our focus today will be on the 6800 GT from BFG Technologies.

Some of BFG's current crop of cards ship in a pre-overclocked state hence the card being named the BFG GeForce 6800 GT OC.  It gives the user an extra boost in the GPU speed, putting it slightly ahead of the competition.  As always, the card comes with BFG's lifetime warranty, allaying any fears about premature breakdown due to the higher clock speed.  Let's look at the specifications of the GeForce 6 series, and the BFG 6800 GT OC in particular and see what makes this card a major contender.

As with most of BFG's bundles, there isn't much in the box other than the card itself and a few accessories.  There's little, if any, filler, focusing only on what's needed to get the card running.  That leaves us with a Quick Install manual (with a more comprehensive version in PDF format on the driver CD), a CD with ForceWare 61.21 drivers, 3D Demos, and nVDVD software.  There is also an additional game CD with demo versions of Splinter Cell - Pandora Tomorrow, Silent Storm, and Painkiller, and finally a DVI-to-VGA connector and Power cable splitter.  Although we tend to lean towards adding a bit more to the package, keeping out the filler helps keep costs under control, and generally people won't need all of the cables and other stuff found with other manufacturer's bundles.
