Some gamers will of course scoop up this card as soon as it hits the shelves, but the rest of us should consider the GeForce 7800 GTX a preview of the exciting new 3D technologies to come.
Nvidia recommends a 330-watt power supply (500 watts if you double up to an SLI configuration ), a lower requirement than the 6800 Ultra's 350-watt specification.
The core clock runs at a default 430MHz, and Nvidia also includes the CoolBits overclocking application (which you need to access via a registry tweak), so you also get the ability to eke out a few more frames.
It might not hurt to wait and see what ATI has to offer, but if you have to have the highest-end graphics right away, at this point we can make no other recommendation than the Nvidia GeForce 7800 GTX.
Nvidia has also highlighted demo clips from the Unreal Engine 3 currently in development at Epic Software to showcase the effects of PS 3.
The Nvidia GeForce 7800 GTX takes up a single PCI Express slot, making it a more compact piece of hardware than the dual-slot GeForce 6800 Ultra.
On CNET Labs' Half-Life 2 benchmark--a test where ATI's Radeon cards traditionally dominate Nvidia's--the GeForce 7800 GTX posted a score of 81.
Same goes for Doom 3 at the same resolution: the GeForce 7800 GTX outpaced the ATI card by 43 percent.
Further, ATI is also set to debut its new graphics chip, code-named R520, reportedly at the end of July.
You still need to connect the card directly to your power supply, though, so if you have a number of components already drawing power, you might have to make a sacrifice.
That the GeForce 7800 GTX threatens the ATI card on the lower resolution test is admirable; the previous-generation GeForce 6800 Ultra consistently lost to ATI on that test.
As for its default performance, the GeForce 7800 GTX dominates on most tests, but we can't say that it's the fastest card across the board.
If you find that a single GeForce 7800 GTX card doesn't give you enough performance, you can always buy two.
Despite its claims to the contrary, however, Nvidia still fails to dominate on the DirectX 9-based Far Cry, a game which the company uses to showcase its new graphics capabilities.
If those images represent the next generation in 3D graphics, Hollywood is in more trouble than ever in terms of giving consumers the most convincing make-believe.

com has reported that Nvidia will announce GT and Standard versions of 7800-series chip, and we anticipate that midrange and budget versions are imminent as well.
At $600, the card sits among the most expensive graphics cards on the market, but the good news is that, as always, the price will drop and the capabilities will eventually wind up on more moderately priced hardware.
