Now that the dual-GPU GeForce 7950 GX2 has hit the streets, the GeForce 7900 GTX is no longer NVIDIA's flagship desktop graphics adapter. But that doesn't mean it should all of a sudden be disregarded and brushed aside as an afterthought for a high-end gaming rig. In fact, the 7900 GTX may even become a more attractive option for some as its price inevitably drops over the coming the weeks and months. It's not like the 7900 GTX has suddenly become a bad performer, just because a more powerful and more expensive option has come along.

We've got a new GeForce 7900 GTX on the test-bench today, courtesy of Gigabyte. The GV-NX79X512DB-RH we'll be looking at here doesn't stray much from NVIDIA's reference design, but it does offer some things that its competition doesn't, and the GV-NX79X512DB-RH is also one of the least expensive 7900 GTX board currently available.

Gigabyte includes a very good assortment of software and accessories with the GV-NX79X512DB-RH. Along with the card itself, we found a complete user's manual, two CDs, a DVD, and a variety of cables and adapters. One the software front, Gigabyte throws in an obligatory driver CD, another CD with a full version of Cyberlink's excellent PowerDVD 6, and a full version of Serious Sam II on DVD. Bundled hardware included an S-Video / HD Component output adapter, a pair of DVI to DB15 adapters, and a dual-Molex to 6-Pin PCI Express power adapter.  Overall, we'd consider this a well balanced bundle.  You've got games, utilities, and adapters to appease a large portion of Gigabyte's target audience.
