7800 GTX SLI and Dual Core processing power?

[lith]

Hello everyone.

I'm set out to buy some serious hardware, and I've been reading the excellent articles
on this page. A question did pop up however, that I can't seem to find an answer
to neither in the articles or on the board.

The test results seem to indicate that an Athlon64 FX-55 acts as a bottleneck when
you're running a pair of 7800 GTX's in SLI, unable to keep up with processing power.
What would the situation be with say a Athlon64 4800+ x2 Dual Core processor?

It'd be mounted on nForce4 SLI.

I'd appreciate any help.

No difference, in todays games.

The application itself must be built for dual core for it to take advantage of it.

A bottlenecked CPU means that the video cards are able to process the geometry from the CPU faster than the CPU can give it. This happens at lower resolutions. As you slowly crank up the resolution and increase quality settings, you are steadily increasing the workload on the graphics card. The CPU delivers the same geometry work at 640x480 or 2048 x 1536 or higher. 7800GTX's in SLI would require more CPU power at higher resolutions than a single 7800GTX of course.

In fact, the 4800+ should be a tad bit slower in today's games.

if you want the serious power, for gaming, go with the FX-57 and clock it up to 3 Ghz. If you do video, and like to do multiple high end tasks at once, go with the 4800+ and clock it up to at least the FX55 (2.6 Ghz)... the dual cores seem to at LEAST get up 200mhz without breaking a sweat...

get a FX-57 and a monitor that can support resolutions upto 2048x1536. play games at that resolution with full AA/AF and there shouldnt be any bottleneck.

Nvidia has beta drivers that support dual cores, and boast as much as a 30% perfomance increase in "some situations".

where might I find these beta drivers for my SLI rig with dual core?

 

[Sentry2]

They're the 81.26 beta's I think...heard they have a few bugs though...I'm just gonna wait nvidia releases them.

Don't listen to anyone here about single core CPUS if the dual core drivers provide a substantial boost, which would eliminate any reason to go for a single core


Also don't listen to anyone who says a 2.4ghz single is faster than a 2.4ghz 4800+ DC in games


An FX-57 @ 3.0 although with air you might not make it would be nice

A 4800+ at 2.8-2.7 would be a close match and perhaps faster with dual core drivers

Make sure you tell us how those drivers work out. I saw the review but I what like to know what a fellow AT'er think of them.

http://www.xs4all.nl/~mlmk/cpu.jpg 81.xx is the first generation is the first generation of forceware that'll support duel-core?..? I think so.

http://www.hardwareoc.at/Geforce-7-Treibervergleich-7.htm

that benchmark on the bottom tells everything what duel-core CPUs are truly capable of, just wait until the Forceware 81.xx becomes official and bugfree, and x2 will eat FX alive.
