Motherboards comes with a review on the EVGA e-GeForce 7900 GTX 512MB PCIe graphics card. EVGA is a NVIDIA house. By that I mean they manufacture NVIDIA based video cards and motherboards exclusively. I've always enjoyed supporting EVGA because they have the best support in the industry period. EVGA chose to use a similar design to NVIDIA's reference design for the e-GeForce 7900 GTX 512MB video card. The GeForce 7900 GTX is a dual slot video card, requiring a PCI Express slot and an adjacent spot next to that slot. Bundling up two of these cards take up about 4 expansion slots, but will deliver outstanding performance.
 EVGA e-GeForce 7900 GTX 512MB PCI-E SLI Review
Each of the e-GeForce 7900 GTX cards has 512MB of frame buffer memory. Today there are cards with 1GB of total memory on the board, like the GeForce 7950 GX2, with 512MB for each GeForce 7900 chip. The memory is clocked at 1.6GHz and a 1.25ns speed rating. Memory bandwidth on the GeForce 7900 GTX is 51.2GB/second effective. All memory chips are located on the front of the PCB, and all cooled by the heatpipe heatsink. As with all recent video cards, the e-GeForce 7900 GT features the PCI Express interface. On top you have the SLI expansion to bundle two of these boards together for extra performance.
The GeForce 7900 GTX is based upon NVIDIA's G71 core, a slightly improved G70 architecture. The GeForce 7900 GTX is one of NVIDIA's first 90 nanometer products, which allowed a speed jump from the 500MHz of the GeForce 7800 GTX to the 650MHz of the GeForce 7900 GTX. The GeForce 7900 GTX has 24 pixel shader pipelines, the same as the GeForce 7800 GTX. I like what EVGA has done with their e-GeForce 7900 GTX EGS's in many respects. If you're looking for the highest performing platform, two GeForce 7900 GTX's set in sli configuration are the way to go at the moment.
The EGS version is matching NVIDIA's reference clocks and is less likely to have problems than an overclocked version. One thing that sets EVGA apart from other companies is the support EVGA puts behind each and every product they sell. If you go onto EVGA's message boards, it is clear that they care about the customer. Lifetime warranty, 24/7 toll free technical support line, and a 90-day Step-Up program add up to make EVGA the choice for NVIDIA products. At the moment two GeForce 7900 GTX's are the fastest NVIDIA platform. This will change in the next month or so when dual GeForce 7950 GX2's can be installed.
When that happens, four GeForce 7900's in Quad SLI will rule the roost at least till the next NVIDIA or ATI card comes out. Many people are waiting for the next upgrade cycle, with the release of Microsoft's Vista in the next year and the inevitable new hardware to take advantage of DirectX 10 to come near the same time.
