Despite BFG's commitment on this front, the GeForce 7600 GT OC's 580 MHz core clock speed is only slightly higher than GT's 560 MHz default core clock. Memory overclocking is restrained, as well, with a 725 MHz memory clock only pushing the GT's default by about 4%. These marginally improved clock speeds should give the BFG card a narrow advantage over stock-clocked GeForce 7600 GTs, but they're unlikely to translate to noticeable performance gains.
BFG sent us a couple of GeForce 7600 OC graphics cards for testing, so we'll be including some SLI results in the mix. The cards are based on NVIDIA's GeForce 7600 GT reference design, which includes dual DVI outputs and exposed "golden fingers" for an SLI bridge connector. Note the lack of an auxiliary power connector; the GeForce 7600 GT can get all the power it needs through a standard PCI Express x16 slot.
The GeForce 7600 GT OC is what we like to call a restickered reference card. Apart from a BFG sticker on the cooler, there are essentially no physical differences between this card and NVIDIA's reference design. Even the cooler is identical to what can be found on NVIDIA's reference cards. Fortunately, the cooler is a variable speed unit that only ramps up fan RPMs under load. This allows for lower idle noise levels, an attribute we'll explore in our noise level tests.
Temperature- or load-dependant fan speed control should be a must have feature for enthusiast-oriented graphics cards, but it's surprisingly missing from many. Fortunately, it seems to be a part of NVIDIA's reference design for the GeForce 7600 GT.
BFG includes a handful of goodies with the GeForce 7600 GT OC, including a pair of DVI-to-VGA adapters and a video output dongle that handles composite, S-Video, and component HD output. A limited version of GameDrive 9.0 is also included with the box along with a number of minor utilities and a driver CD. The GeForce 7600 GT OC's most attractive extras aren't really tangible, though. BFG covers the card with a lifetime warranty, and also includes free telephone support for North American users. The tech support hotline is open 24 hours a day, seven days a week, and although seasoned enthusiasts may have little need for hand holding, less savvy users should appreciate the ability to reach out and touch someone for assistance.
