CUDA on PCI 1.0

Hi guys,
I got motherboard ASUS p5gd1 pro (PCI-express v1.0), and i’ve just ordered Gainward gtx 275 896mb, and chieftec 14cs 600W.
Will it work fine? I will use this set only for programming.
How much slower will it works, than with pci 2.0?
What do you think about this set?

Thx for all help, and sorry for english;)

It will work.

Transfer between host and device can be up to two times faster on PCIe 2.0. Internal bandwidth in unaffected.

I have gone through a similar exercise just recently; you can read about it here:
Hope it helps

Thx guys!
