BFG Technologies GeForce 7900 GT OC Review

Author: Ryan Shrout
Manufacturer: BFG Tech

Card and Features

For the most part, video card design has been unimaginative since the introduction of the NVIDIA 6-series of graphics cards.  The board partners that NVIDIA works with, including BFG, XFX, EVGA, Asus and others, are all basically taking the same NVIDIA reference design video card, changing the sticker on the heatsink fan and then shipping them to customers.  With design cycles and tough pricing-based competition, all of the vendors are looking to get product out quickly and cheaply, and this is one way to do it.

You can see here that the BFG 7900 GT OC card looks just like our reference sample did from NVIDIA back in March.  The 7900 GT features a single slot cooling solution that is a welcome change from the dual-slot 7900 GTX and ATI X1900 line of cards, that is for sure.  A single PCI Express power connector is located on the rear of the card for power supply connection.  The noise level of the cards is actually a bit louder than those on the 7900 GTX simply because the smaller heatsink needs the fan to run at a faster RPM in order to properly cool the GPU underneath. 

As you saw on the first page in our specfications table, the BFG 7900 GT OC card is overclocked over NVIDIA's reference specifications to 475 MHz core and 1360 MHz memory clocks.  The reference speeds are 450 MHz and 1320 MHz respectively, so BFG's overclocking is a modest 5% or so on the GPU.  We'll look at overclocking these cards even further than BFG does in a later section.

Again, you can see the BFG 7900 GT OC uses a single slot configuration and includes two dual-link DVI connectors for the most robust monitor support you can get on consumer graphics cards.  Support for two of Dell's 3007 30" monitors at resolutions up to 2560x1600 is built in.  The TV-out port allows the user to output either composite or component output to a standard or hi-def television. 

Included Features

All vendors try to add some value to their video card by including some things in the box that users will either want or need in their gaming or computing experience.  This task is pretty difficult though as AICs are always looking to get a lower price as well as better value for the customer.

BFG has included two DVI to VGA adaptors for those using older monitors as well as a power adaptor for power supplies that don't yet have the dedicated PCIe power connection.  It is recommended that you attach each of the Molex power connectors to a different line out of the PSU for the best power distribution across the system to the power hungry 7900 GT. 

The other dongle supports three different types of TV output -- composite, S-Video and component for HDTV support.
