Questions about DV6t Quad Ed.

http://www.shopping.hp.com/webapp/s...otebooks&series_name=dv6tqe_series&aoid=35252

This model has customized & quick-ship option.
I notice the customized version is fitted with Geforce GT 320m - For i7 processor (no other option), while the Quick-Ship model is fitted with GT230m WITH Physx.

I've heard about Physx before, and I always think it is another component bought separately (at least for PC desktop 1-2 years ago). So, is this Physx processor always present with all Geforce GT230m & 320m series, or does HP actually fit this additional processor as a bonus ?

I look on NVidia's technical specs for 320m & 230m, and Nvidia specifies that they are both Physx-ready. What does "READY" mean here ? Ready to be fitted with an optional Physx feature, or does it mean both have already integrated the Physx into 320m & 230m ? ...or do I misunderstand something ?

 

Physx is already integrated onto those GPUs. you don't need anything extra.

If you want you can add an external GPU (using the diy vidock) and let your internal GPU be a dedicated Physx card, see this post:

Thank you. That's all I need to hear.
I'll choose to customize then. No physx battle anymore.
