Yep, I had the same problem.
Your new computer probably has DirectX10 already on it right?
You can hit START then type DXDIAG in the
Search box to find DXDIAG, then click the link to run it.
(The DXDIAG is the DirectX Diagnostic tool included with Windows)
The problem is, you need the DirectX9 drivers as well.
Go download the latest X9, and it will work.
DX10 is not fully backwards compatible with DX9 (ask MS why).
It seems they [X9 & X10] can both reside on the same machine though.
My DXDIAG still says that I have X10 even tho I installed the X9 after X10.
Anyway, I installed the latest DirectX9 and it worked with the 8500GT.

Not recommended. Get the 8800 instead.
Wait for the pre-Cristmas sales to get one cheaper.

In my case, I got a pretty sweet deal on a system that had the 8500 already on it.
It was not a custom build, and the 8800 would cost more to buy then than later when FPSC X10 is released.
SO...
System + 8800_on_sale_later
< System + 8800_regular_price_now
This way I get the System (Q6600 + Vista) to use while I wait for the other goodies.
For me, buying the 8800 now would be the waste of money.
