can we play games as we do today witohut the card for another 1yr atleast?
after that will our games refuse to run without it?
after that will our games refuse to run without it?
how many years?
Also, will the performance of our existing systems receive a big hit within the next 2 yrs?

I'm not worried about the PCI bus being a bottleneck for this physics processor for a number of reasons. For one thing video cards barely utilize the 2X agp bus because of the fact that once the textures are on there, they stay there and are not shared with the system memory except on budget systems. Even with a 16X PCI express bus, it's terribly slow to use system memory for texture storage which is why people like to stick with onboard memory therfore the transfer of data from the system bus to the graphics card is limited to it being "loaded" and I unloaded.
Now physics calculations are much much different than graphics because of the fact it's mostly wireframe models and other calculations. These don't take up a very large portion of memory but instead take a lot of processing power. It's like distributed computing, like SETI. Seti sends some packets (fairly small) to the computer doing the work load which it crunches. While this takes hours, it's still fairly small bits of information (at most 1MB) but it still takes a long time to calculate. This is also like prime 95, a small program but the calculations takes ages with little memory usage (except when using benchmark mode).
So having a "physics calculator add in card" in the PCI slot isn't such a bad idea because of the fact that the work load it recieves are fairly small packets (no where near 133MB/s) and all this calculating is done on the card which can have an unlimited bus speed (assumes the card comes with a little bit of memory). Remember we're in the early stages of working with these physics calculations, in the furture these calculations could take upwards of 100MB! But for now were dealing with relatively simple calcualtions (in comparison to what they could be) that simply take a lot of horse power to compute and no so much memory.
So here is how I can see it happening:
1. Game is loaded into video card memory/system memory and right before you see the game's interface, Physics calculations are sent to the add in card.
2. Add in card has a little bit of it's own memory and the tasks are queued
3. Physics processor does all the calculations it needs (things queued in memory aren't there for very long like 100ms if the task is relatively simple)
4. Sends calculations it's done either directly to the graphics card or to the processor then the graphics card
5. Now you see the video game's interface (Your in the game now looking around)
6. Physics add in card is waits for more tasks and this cycle continues.
(Keep in mind that this queueing, calculating and send the information back is all happening in fairly short order)
Anyways it's not the amount of bandwidth the bus can handle between the add in card and the system board but how fast it moves this data (latency) that will be an issue because calculations aren't graphics, just simple binary code that needs to be quickly calculated.

Well it's kind of related.
Seeing 100 bolders rolling down a hill instead of 5, seeing stream of water really flows instead of being stationary; See the hair and cloths of your in-game characters flutter. It's not only a "physical" effect but as well as graphical.

Who is going to pay ANYTHING for it if you can't use it right away? It'd better come bundled with a game or multiple games that show a direct improvent thanks the PPU.
for much time will the ppu remain optional and for how many years can we play games as we do today just fine without a ppu?
I'm betting more people will buy it when they start flipping over the boxes for the latest games and the PPU is listed in the "Recommended" section.
I'll get it the day it comes out. But I'm crazy and I blow cash on computers just to stay "cutting edge":disgust:

Are you kidding me? Do you know how many people ignore that and think integrated graphics are fine still? Or how many people think a 5200FX is a kick ass card? There are a lot of stupid casual gamers out there, let me tell ya. PPU won't be mainstream till 2nd gen.
If they come out with a PCI-e x1 slot version, I'll probably have to get it just so I can make use of that slot on my SN25P!

Like most things, I'll wait till it has matured a bit and has significant support, than I'll buy@the "sweet spot" for price/performance ratio.
i'll buy it in my next rig when i go dual core, get 7800's in SLI, and buy windows x64....
for all of those...there will be more drivers/apps/games/OS's that cna take advantage of it....and they'll have a better version than the first they came out with

How long until video card maufacturers start integrating the PhysX PPU onto their graphics card?
Whats the point of doing that? The ppu has nothing to do with graphics, its a physics chip.
Plus after watching the nvnews ageia e3 video the guy said that they'd love to use a pci-e 16x slot because the chip is bandwidth hungry. And also the chip needs its own high speed gddr3 memory.
If you put this on a video card you'd be stealing most of its bandwidth and memory.
i hope they dont put it on an x16 slot..then you'd need 4 x8 lanes and another x16 PCI-E bus for next gen SLI and a PPU...
Have you seen the list of upcoming games set to support this? This board is going to be supported by City of Villians, so I like to spend the $250 to get it. I'm already addicted to COH.
That's just for the upgrade, imagine the cost if you have to build an entire new system to play the next hottest games, and then upgrage every year to keep up.
