I'll just copy and paste (pun intended) something I wrote in another thread:

As for raw numbers, the N900's graphics card works up to 14MPolys/s, while the 3GS is theoretically supposed to be able to reach 28MPolys/s, but as described above, is underclocked to only 7MPolys/s, which makes it somewhat inferior.

Presumably worst case it would require a third-party capture application, right? Although I would prefer if you could adjust it in the official one.
It gives me so many ideas though. Mounting NFS and capturing directly to my server. I already suspect I will have a go at using it as a webcam over 3G, hehehe.
All stuff I should have been able to do on the Xperia but Windows Mobile software sucks and is nearly all commercial. I wouldn't pay $15 to be able to do these things, but I would happily tinker with open-source software to do it.
