The new ...
Nvidia GeForce 7800 GT
This one is the little brother of Nvidia's newest High price tag card the 7800 GTX.
The highest end ATI card, the Radeon X850 XT PE, falls short of this new Nvidia card, and at a $100 higher price tag...

Nvidia's new GeForce 7800 GT features the same accoutrements as its older brother, the GeForce 7800 GTX, but with a slightly less powerful GPU. The card will be available for purchase at an MSRP of $449. Following the tradition started with the GTX launch, GeForce 7800 GT based cards are available for purchase right now.
Nvidia didn't design a new GeForce 7800 GT chip from the ground up. Much the same way that CPU manufacturers practice speed binning, GPU manufacturers create new, lower-priced products using chips that couldn't quite make it to flagship status. The GeForce 7800 GT has the same 302 million-transistor GPU as the GeForce 7800 GTX, except portions of it have been shut down.
The PCI Express GeForce 7800 GT has 20 pixel pipelines, four pipelines fewer than the flagship GeForce 7800 GTX, but that's still four more than the GeForce 6800 Ultra. The GeForce 7800 GT also has seven optimized vertex pipelines, compared to the eight that are available on the 7800 GTX. Nvidia also dropped the core speed of the GeForce 7800 GT down to 400MHz; the 7800 GTX, in comparison, has a 430MHz core.
The GeForce 7800 GT comes with 256MB of DDR3 memory, like the 7800 GTX, but the GT's memory runs slightly slower. Memory will be clocked at 1GHz (500MHz double-data rate).
Since the GeForce 7800 GT has the same core as the GeForce 7800 GTX, you'll find all of Nvidia's new technologies onboard. Support for Shader Model 3.0 will come standard. Other Nvidia-specific features include HDR (high dynamic-range lighting), transparency sampling, and PureVideo. High dynamic-range lighting is used to simulate a wide range of light intensities, ranging from blinding sunlight to the darkest shadow, in a single scene. Transparency-sampling technology allows the card to clear up jaggies for lines drawn in the middle of a polygon instead of on an edge. PureVideo allows the GPU to output progressive video and to encode up to 1080i for HDTV output, as well as to accelerate and improve the quality of video playback for MPEG-2, WMV, and WMV HD on the video card.
| GeForce 7800 GTX | GeForce 7800 GT | GeForce 6800 GT | Radeon X850 XT PE | | Pixel Pipelines | 24 | 20 | 16 | 16 |
| Vertex Pipelines | 8 | 7 | 6 | 6 | | Core Clock | 430MHz | 400MHz | 350MHz | 540MHz |
| Memory | 256MB | 256MB | 256MB | 256MB |
| Memory Clock | 1.2GHz | 1.0GHz | 1.0GHz | 1.18GHz | | Memory Interface | 256 bit | 256-bit | 256 bit | 256 bit | | MSRP | $599 | $449 | $399 | $549 |
Nvidia recommends a 350W power supply for single-card GeForce 7800 GT systems and a 500W power supply for SLI systems with two GeForce 7800 GT cards. The single-slot GeForce 7800 GT requires the same 12-volt power connector found on other high-end Nvidia-based cards.
The GeForce 7800 GT puts up serious performance numbers at the $450 price point. The ATI Radeon X850 XT PE offers some fierce competition, but the card simply can't compete at the same price point as the GT. In every single one our tests, the GeForce 7800 GT comes away the clear winner against the Radeon X850 XT. With the release of the GeForce 7800 GT, be on the lookout for falling prices from both GPU manufacturers. The GeForce 7800 GT will push GeForce 6800 series GPUs down the price ladder one notch, and ATI's Radeon X800 lineup will have to match the drops to remain competitive.

The Geforce Cards typically are "More Bang For your Buck" compared to the ATI Cards. Geforce cards are easy as heck to update as well, the Drivers come in a neat little package. |

I'm all about Nvidia recently. They are playing all their cards right. I'm really glad they are making the GPU for the PS3. *geeks out* |

I love BFG. All their Geforce Cards come with lifetime warranties!
