EVGA e-GeForce 7800 GTX EGS

Introduction, Specifications & Bundle

Almost immediately after we begun working with NVIDIA's reference GeForce 7800 GTX cards in the days and weeks leading up to the launch, we were contacted by a handful of NVIDIA's launch partners and informed that they'd have retail hardware ready to coincide with the official announcement of the GeForce 7800 GTX.  Leadtek, Gigabyte, BFG, MSI, Asus and EVGA were among the first to contact us with some specifics regarding their respective GeForce 7800 GTX cards.  The first one to send us a sample for review, however, was EVGA.

The e-GeForce 7800 GTX we'll be showcasing today is one of three 7800 based products EVGA currently has in their line-up, but we know a fourth model with a custom cooling solution should be available in the not-too-distant future as well. The e-GeForce 7800 GTX we have here, part number 256-P2-N528-AX, is essentially a duplicate of NVIDIA's reference design, with slightly different default core and memory clock speeds and a custom decal on the fan shroud.  EVGA's other 7800 GTX packages, part numbers 256-P2-N538-AX and 256-P2-N525-AX, are very similar, but one ships with a copy of Battlefield 2 in addition to what we're going to spotlight for you here, and the other has a lower default core clock speed...

EVGA included a nice assortment of software and accessories in the bundle for their e-GeForce 7800 GTX.  Along with the card itself, EVGA included a small folder that contained a basic user's guide, a couple of EVGA stickers, a driver / utility CD with trial versions of SnapStream's Beyond Media and Ulead's DVD Movie Factory 3, and EVGA's ResChanger 2005 tool, and another disc with a copy of Cyberlink's PowerDirector software. EVGA also included a pair of DVI-to-DB15 adapters, a dual-molex-to-PCIe power adapter, an S-Video cable, and a small breakout box that housed S-Video and composite inputs, and component and S-Video outputs.  The breakout box and PowerDirector software compliment the e-GeForce 7800 GTX card's ViVo (Video-In / Video-Out) capabilities.

EVGA's bundle was decent, but we would have liked to have seen a couple of other items included as well. Noticeably absent in the e-GeForce 7800 GTX's bundle was any type of game or full-version DVD playback software. Although, the trial version of Beyond Media can playback DVDs and the 256-P2-N538-AX model is available for only a few dollars more, that includes a copy of the excellent Battlefield 2.
