BFG GeForce 7800 GTX OC

0 thumbs up

NVIDIA most definitely has been on a roll as of late, with the introduction of a very successful 4th generation motherboard chipset with the nForce 4, and more recently with their GeForce 7 series launch and market introduction of the GeForce 7800GTX.  In these launch articles we often times work with platform "reference" hardware for testing direct from the core technology OEM and soon to follow, we cover retail level products from various board partners as they are released into the channel.

With the NVIDIA GeForce 7800GTX launch however, the Silicon Valley based 3D Graphics giant seems amazingly strong and confident in their roll-out, as is evident in the wealth of information we've been receiving on various incarnations of the final retail product from virtually all the top 3rd party Graphics Card suppliers.  Not to mention their immediate availability in the retail channel which speaks to the fact that these new GPUs are flowing pretty freely off the line at NVIDIA's fab partner, TSMC.

We have many retail ready GeForce 7800GTX cards in the queue for analysis and showcase here at HotHardware.com and one of the first manufacturers out of the gate was BFG with their "GeForce 7800GTX OC".  Sporting a goosed up core GPU clock at 460MHz (30MHz faster than the NVIDIA reference design) and GDDR3 cranked up a notch to 1.3GHz (1.2GHz is the stock GF7800GTX spec), the card is a true testament to the fact that NVIDIA is perhaps holding back a bit, saving some extra juice to perhaps counter whatever ATi's next gen product brings to the fight.  For now however, the spotlight is on NVIDIA, or shall we say BFG?  Bringing in the "big guns" is what this new graphics card suggests it will allow you in your gameplay. Right then, let's lock and load.

* Standard NVIDIA GeForce 7800GTX GPU Engine clock = 430MHz
* Standard Memory speed = 1.2GHz

We've provided the full specifications and features of the BFG GeForce 7800GTX for you here but we won't re-hash what we've already covered in our launch article in terms of the overall architecture.  It's very safe to say that literally the only thing that distinguishes this BFG card from the NVIDIA reference card we looked at in June, are its Core GPU and Memory clocks, which as we mentioned BFG has tested and warranted to work at 460MHz and 1.3GHz, respectively.  Without even so much as a cooling modification BFG was able to offer these speeds preset and out of the box, which again just goes to show how comfortable NVIDIA is yielding these new 24 pixel pipe GPUs in high volume production.

  

  

Since this is a high end "enthusiast" class card, BFG decided to take the high road as well with the product's pack-in bundle.  Included with the GeForce 7800GTX OC are an assortment of cable assemblies, one which is a break-out adapter for connecting the card to a High Def TV via a Component Y/Pr/Pb connection.  Also included are two DVI to VGA converters, an S-Video/VGA VIVO dongle, and a dual 4-pin to single 6-pin PCIe Graphics power cable.

Beyond the hardware, BFG tossed in an assortment of software, including NVDVD 2.0 Multimedia Player, Video Studio 7 SE video editing software and GameDrive 9 which essentially allows you to make virtual drive copies of your CDs so that gameplay without the need to have a game CD in the drive is possible.  Then of course there's a full-up version of the impressive looking FPS game, Far Cry, which will afford consumers a taste of the benefits of leading edge DX9 graphics in action on your new BFG card.  Hats off to BFG for including this great game title.  Instant gratification is a beautiful thing.  Finally, just to ice what is already a well dressed slice of technology cake, BFG includes a tee shirt and a set of Teflon mouse slick pads, which really worked well in our rigorous and highly scientific frag-a-thons, err... testing sessions.
