Here's a quote from the article:
On paper, the G965 Express chipset's GMA X3000 graphics core is a marvel. It's the only integrated graphics core with a unified shader architecture, it supports Shader Model 3.0 with 32-bit precision throughout, and it's loaded with video output options. With a 667MHz core clock speed, the X3000 should offer blistering performance, as well. But by and large, it doesn't. Sure, the GMA does well in 3DMark06. However, in actual games, the X3000 is consistently beaten by the Radeon X1250 in AMD's 690G chipset, and it struggles to keep up with Nvidia's older GeForce 6150 series IGPs. That's if the X3000 can run the games at all. As we saw with Battlefield 2 and Oblivion, Intel still has some very basic compatibility issues to address.
The GMA X3000's problems don't end with 3D performance, either. Intel's Clear Video processing suite also has issues, including choppy 1080p WMV HD playback and lower scores in HQV's DVD playback tests than competing solutions.
