Freezing issues with Nvidia FX4000 & Premiere CS5

Question

Question, I'm editing a 1080p animation project in CS5, on an i7 3GHz, Win7 64bit, with Nvidia FX 4000, 15GB of RAM and about 500GBof disk space, plus an additional 800GB of scratch disk.
I'm editing primarily 32 bit frame sequences with some effects. Less than a minute into the project and about 6 layers deep I freeze when trying to build previews (lost the Mercury Engine after layer 4) and freeze when trying to export, its like I basically get stuck. Why is this happening, it makes no sense, there's enough system resources. Would appreicate any feedback.

You aren't the first to post that an i7 machine with nVidia card seems slow.  Search this forum for i7 and slow.  I can't recall whether anyone came across a workaround or solution.
Have you checked your power management options?  Is it possible the processor is somehow not being brought out of low power mode?
Do you have an alternate video card (e.g., made by ATI) you could try with it?
By the way, make sure and close and restart Photoshop after making configuration changes, just to make sure it's using the changes.  Just checking boxes and trying things could mean that it's still using the same old settings and the results are therefore inconclusive.
