At first glance, there seems to be very little difference between the cards. But if we look closer, it's obvious the Gigabyte GeForce 7900GTX's offering is faster than the other cards. The most important thing to note is the minimum fps - the Gigabyte GeForce 7900GTX is able to maintain a 70 fps minimum at default setting up to 1600 x 1200. Both the ASUS EN7900GTX and Leadtek PX7900GTX is just shy of 60 fps, though the Leadtek is very close to the Gigabyte card at 1024 x 768. With AA and AF enabled, we see a slightly different story. At 1024 x 768, both the ASUS EN7900GTX and Gigabyte GeForce 7900GTX is neck to neck, while the Leadtek brings up the rear. At 1280 x 1024 and 1600 x 1200, it's the ASUS EN7900GTX that takes the lead, albeit a very small one.


Even at 1600 x 1200, we barely see a difference between all three cards. No doubt we're system limited here and the differences we're seeing are mostly normal variations between runs. Generally, we see all three cards offer the same level of performance, though the Leadtek PX7900GTX seems to be slightly behind at 1600 x 1200 with AA and AF enabled.

Usually, we will look at Splinter Cell: Chaos Theory before making our conclusion. But from the looks of it, we really don't need to.  Since all of these three cards make use of the reference board, cooling solution and specification (core and memory clock), we saw an equal offering from all of them. The differences we saw in these results are mostly system related and an inherent factor of the GeForce 7 series (at least in the GeForce 7800 and 7900 series). While the Gigabyte GeForce 7900GTX seems to have the slightly higher performing offering, there's little guarantee that the one we got for testing and the one you'll buy will perform in the same manner.

So, we found ourselves in the same predicament as we did with the the Radeon X1900XTX round up. The deciding factor will be other factors beside performance, mainly bundle, price and support. Since support and price vary from country to country and region to region, obviously we can not include that factor in our evaluation. It will be up to you to decide which card is best for you, however we can honestly say that with whatever brand, you'll likely have the same level of performance.

Conclusion:

Since all three cards are basically the same card, running at the same clock, we expect little performance difference between them. They also come with pretty much the same bundle, except maybe for Gigabyte's offering. However, the lack of bundle is offset by the slightly fester performance. Personally, we prefer the Leadtek PX7900GTX - it has a slightly up to date game bundle and comes with a more practical, yet safer box. Yes we know, these are minor details but that's why we call it a personal opinion.  These small differences are hardly enough for us to recommend the Leadtek's offering over ASUS' or Gigabyte's.

Like what we concluded with our Radeon X1900XTX round up, unless you get the slightly higher clocked GeForce 7900GTX, all GeForce 7900GTX are virtually the same. Sure, there will be slight differences in performances and bundles, but these are small differences. Since performance and bundles don't differ much, we think you should choose the card you will be more comfortable with. For example, if you have two analog monitors and want some multi monitor action, go look for a GeForce 7900GTX that comes with two DVI to analog dongles. If you are more concerned with price or support, then go with a vendor or retailer that you know best or have good experience with.
