Notice the SLI like connector at the top. I wander if you can connect a
few of these together? Also, the molex connector on the side. Would 25W
be too much for the PCI-E 1x slot to handle? Maybe this would just be
for the regular PCI slot.

Also, they have on their site a
program for you to download to show you how limited your CPU would be
for their Novodex API. When I ran the demo called big bang, I was
getting 5fps on my athlon64 3500+ and 6600gt while viewing only 14000
blocks moving on the screen, something the PhysX processor could handle
easily. Also, I would think that instead of making just one physics
engine for all games, they would just make an API like DirectX or
OpenGL to run on their card, and let the game designers design their
own physics engine using that. Which seems more likely to happen, if
not now, then in the future.

Also, they have Ubisoft, Valve,
Havok, and Epic taking advantage of the card, so Unreal Tournament
2006, Half-Life 3, and Splinter Cell 4 will all take advantage of this
card. If those engines and games all use this card, then so will other
game makers, and eventually you may have to buy a PPU along side a GPU
to make games run at max. settings.

Although using a PPU may
also end up the same as the APU did. Buying a PPU card would be about
the same as buying a brand new sound card just for EAX 3.0 support and
better sound quality, which in some peoples opinions isn't worth the
money.
