I have a PPU card. And, I played GRAW2, using the setup in sig @ 1920x1200, settings maxed out.

It's gonna take some serious GPUs to do both physics acceleration and rendering at the same time. I mean, some of the physics acceleration in GRAW2 drags frames down drastically (even @ 1600x1200). As the physics in GRAW2 is mainly “effects physics” (and not “gameplay physics”), this drag must be GPU and not CPU related.

For the sake of argument: Try imagining any nVidia GPU running Crysis in DX10, HD, high graphics settings and calculating the physics acceleration of the game - at the same time. I think you get the picture by picture by picture by picture... frame rates

Contrary to what Anandtech writes and what has been indicated in various statements on the acquisition (including the press releases from nVidia), I still think we will see a PhysX technology implementation that goes beyond merely using the PhysX software on nVidia GPUs (combined with minor GPU architectural optimizations/improvements). Time will show…

On a side note: To judge from Ageia's US patent application, this acquisition is what they were hoping for, from the very beginning of their effort to bring real-time physics acceleration to 3D environments:

[...] It is readily foreseeable that a PPU and a GPU will be combined on a single interface card. That is, both chips will be physically mounted on the same card (AGP or PCI-Express), but not directly interfaced with one another. Ultimately, a single interface card having a directly interfaced PPU-GPU combination is expected, but such a combination is probably a generation away. So too is a combination within a single chip of PPU and CPU functionalities.
Paragraph [0061].

That the team at Ageia (in all probability) didn't make a lot of dough through selling now - due to financial difficulties - lies IMO entirely on their inability to understand the diversity of the enthusiast market segment. That is, not only focusing on the gamers, but also the benchers, overclockers, modders and crunchers/folders. Talk about Xtreme disappointment! When Ageia tried to right this huge mistake, it was way too little, way too late.
