NVIDIA GeForce 7900 GT Graphics Card

The first reaction when we installed this card was amazement at the size of the cooler. For such a high-end card, NVIDIA used a pretty small stock cooler. In fact, it's the same cooler used in the GeForce 7600 GT! We knew instantly that the die shrink alone had been very effective in lowering its power output.

The GeForce 7900 GT is really just an lower-clocked version of the GeForce 7900 GTX. The GPU itself doesn't lack any feature that its bigger brother has. All that differentiates it from its bigger brother are the lower core and memory clock speed, as well as the smaller framebuffer and cooler.

Since the GeForce 7900 GT doesn't require as much power as the GeForce 7900 GTX, it's much easier to run two of these cards in SLI, if you wish to do so. Although the testbed was only running on a non-SLI certified 480W PSU, it had no problem handling both GeForce 7900 GT and GTX SLI configurations.

Of course, we are not saying you can safely run two GeForce 7900 GT cards in SLI with just about any PSU. But we can certainly assure you that you will have a much easier time running the GeForce 7900 GT in SLI configuration than you will with the GeForce 7900 GTX.

Because of the relatively cool-running GPU, this card is far more overclockable than the "fully loaded" GeForce 7900 GTX, even with the skimpy little cooler. With improved cooling, it could possibly overclock even higher.

But even without overclocking, this card is fast! This card is not only much faster than its predecessor, it actually overshadows the GeForce 7800 GTX, not only in terms of performance, but also in power consumption, thermal output and most importantly to the buyer - price. In esssence, the GeForce 7900 GT offers the same level performance as the GeForce 7800 GTX but at a much lower price, power consumption and thermal output.

Overclocking it further boosted this card's performance. In fact, we came quite close to the performance of the new GeForce 7900 GTX when we overclocked the GeForce 7900 GT. With a better cooler and some luck, you could possibly obtain better overclocking results than we did.

Both its fantastic performance and overclockability will make many gamers very happy. But the biggest winner will be NVIDIA. Thanks to the smaller manufacturing process, and trimming of the transistor count, the GPU will be cheaper to make than their predecessors. And NVIDIA is sure to sell loads of this card.

Because of its great combination of price, performance, overclockability and power consumption, the NVIDIA GeForce 7900 GT is no doubt one of our current favourite cards. In fact, we love it so much we think it deserves our Editor's Choice Award! Congratulations, NVIDIA!

* Our New Review System

ARP is committed to developing new ways to improve your experience with us. As part of our continuous efforts to improve the value of our reviews to you, we are implementing a new review system.

This new review system is designed to allow you to quickly receive information on the latest hardware. This new system also allows you to quickly get the gist of the review without reading through it. This can be very useful, especially in situations where you need to make a quick purchase decision.

In this new system, we start with a Product Overview whenever a company sends us a press release about their latest product. We shift through extraneous PR-talk to create a straightforward summary of the product's features as well as its specifications. This allows you to quickly find out all the pertinent details about the product, without reading through official press releases.

When we receive the product for review, we will quickly take photos of it and create a Pictorial Review. The purpose of a pictorial review is to allow you, the reader, to quickly examine the product visually. It may help you make better purchase decisions, especially if you cannot wait for the full review.

After thorough testing, we will post a Comprehensive Review of the product. This adds on to the pictorial review with comprehensive test results and our final conclusion on the product.

But no matter whether you are reading a Pictorial Review or a Comprehensive Review, you can always read the summary of the review as well as examine the product's specifications right on the first page. In all our new reviews, we will maintain the first page as a Product Overview page. If the product is listed in PriceGrabber, you can also check out the lowest price online.

We hope this new review system will make your experience a lot more enjoyable and informative!
