This is the first motherboard we have tested with Intel's GMA3000 IGP on board. According to Intel, the new GMA3000 series deliver much better performance than previous GMA 9xx series. Below is a table illustrating the major differences between the two chipsets, taken from macrumors.com:

The graphics engine of the Intel® Graphics Media Accelerator 3000 family consists of a scalable array of symmetric processing components known as execution units (EUs) which can be programmed to dynamically process graphics or media data alike. Programmability of the EUs adds flexibility and enables support for future graphics and media usages by upgrading the driver. Execution units support dynamic load balancing, multi-threading, and multi-functional data processing, resulting in increased performance to enable a more compelling gaming and visual experience for main stream users. Intel’s next generation architecture shows Intel’s continued innovation by delivering greater flexibility and performance to meet the needs for the current and future consumer and corporate applications.

The new Intel Graphics Media Accelerator architecture with its greater performance and flexibility will be the basis for many new consumer and corporate applications. For consumers, the Intel® Graphics Media Accelerator X3000 engine supported on Intel® G965 Express chipset has been optimized for enhanced 3D to allow for greater game compatibility and realism with new video and display features to deliver a theater-like
entertainment experience through Intel® Clear Video Technology. For corporate users, Intel® Graphics Media Accelerator 3000 engine incorporated in Intel® Q965/Q963 Express chipsets continues to offer stability, ease of use, and lower power consumption, in a cost effective solution. The Intel® Graphics Media Accelerator 3000 family engine is eligible for the Microsoft Windows Vista*Premium logo.

Intel’s next generation Graphics Media Accelerator that provides new levels of graphics and video responsiveness in a cost effective solution. The Intel graphics engine is integrated into the Graphics Memory Controller Hub (GMCH) and enables a low power, reduced form factor solution compared to power-hungry discrete graphics cards:

Intel currently ships two versions of GMA3000 series, the G965 and Q965 chipsets:

Their main differences is that the Intel G965 chipset is clocked at 667MHz (vs 400MHz), supports up to 384MB shared memory, SM3.0, Vertex Shader 3.0, Pixel Shader 3.0, Hardware Geometry Processing (Transform and Lighting (T&L), High Dynamic Range (HDR), Advanced De-interlacing, MPEG-2 Hardware Acceleration, WMV9 HD decode and Advanced Display Connectivity (HDMI) output.
