The GMA X3000 is an onboard graphics output device, on board graphics
has historically been much slower and less feature packed than their
alternative PCI-E or AGP brothers.
This remark on a review of a trade show sums this up.
"Admittedly the X3000 sounds impressive - by Intel standards mind you
- with support for Shader Model 3 and DirectX 9.0c. Mainly though it's
positioned as an output device for media PCs, and integrates features
like hardware de-interlacing for video."
This basically says that Intel made this device as a means to display
graphics and cope with low end graphical demands but nothing much more
This graphics card was only finally released (including all system
specifications for manufacturers) on the 8th of August this year so
the chances of finding any final release or fully completed
motherboard benchmarks is going to be hard.
As taken from here
"Intel has updated the final specifications for G965 and Q965 Express
chipsets. Intel originally intended to use same integrated graphics on
both G965 and Q965 Express chipsets, but this update shows that they
have decided to use two separate graphics core?GMA X3000 for G965
Express and GMA 3000 for Q965 Express. G965 Express with its GMA X3000
graphics core will support DirectX 9c, DirectX 10, OpenGL 1.5,
Hardware vertex and pixel shager model 3.0 features. The GMA X3000
will have a 667 MHz graphics core clock with support for high dynamic
range and Intel Clear Video Technology for enhanced video playback."
It will also be able to cope with the Aero interface of the new
Windows Vista when it is finally released.
This website is the offical Intel white paper on the graphics device
One section of this white paper reads
"The Intel® G965 Express chipsets that incorporates Intel® Graphics
Media Accelerator X3000 runs at 667 MHz and supports a dual channel
memory bandwidth of up to 12.8 GB/s and dynamic video memory of 384
As you can see, the Nvidia 7900GT that you were thinking of purchasing
yesterday is a much better graphics card with its 512MB of dedicated
video memory (on the X3000 I believe the memory is shared with your
system memory reducing your 2GIG of system memory down to 1.62gig).
The 7900GT has a memory bandwidth of 42.2 GB/s almost 4 times faster
than the X3000.
On board graphics cards have never been as powerful as their PCI-E or
AGP counterparts but for what they are they will easily suffice for
watching movies and playing low end games and high end games at much
The X3000 graphics processor is not a low quality graphics processor,
when compared to the 7900GT and the 7600GT you would be much better
off opting for the 7900GT graphics card.
I hope this gives you enough information.
