Although nVidia recommends a 500W power supply for running two GeForce 7800 GTX cards in SLi, I think that our green friends are definitely erring on the side of caution. Obviously the quality of the power supply comes into the equation, because the 460W Tagen power supply in the TrustedReviews graphics card test rig had no problems handling a pair of cards.
One criticism that was laid at the 6800 Ultra when it launched was the fact that it took up two slots inside your PC – a fact that was made worse when ATI launched its X800 cards in single slot form factor. Thankfully nVidia has learned from its earlier experience and the 7800 GTX is a single slot card, albeit a very long one. The 7800 GTX also seems to run both quieter and cooler than the 6800 Ultra.
Now, don’t expect to see a plethora of different designs when you’re looking to buy a GeForce 7800 GTX card, since most board partners have just gone with the nVidia reference design, XFX included. It’s more likely that the differentiator between boards will be the clock speeds (as seen here) and the bundle that you get.
What you’re sure to get is dual DVI connectors, since this is part of the reference design. This is a great feature on any card and allows you to connect two LCD screens up digitally, for the best combination of desktop real estate and image quality. However, if your LCD only has an analogue connector, or if you want to use a CRT monitor, XFX has supplied two DVI to D-SUB converters in the box. If you’re wondering why anyone would want to connect a card like this to an old technology CRT monitor, keep reading and all will become clear.
Taking a look at monitors for a minute, the average PC user with a decent setup is probably using a 17in or 19in LCD screen with a resolution of 1,280 x 1,024. A true enthusiast user may have forked out the extra cash for a 1,600 x 1,200 20in or 21in LCD screen, while the totally loaded enthusiast may have treated himself to a 23in or 24in widescreen LCD with a resolution of 1,920 x 1,440. But the problem with all those screens, even the top end 24in widescreen display, is that they can’t produce a high enough resolution to do these cards justice.
