Pci-e 2.0?

I would like to know if anyone is running a 2.0 card on a 1.0 slot board. I want to get a 8800gt, but I keep finding mixed reviews about compatability. I have a socket 939 mobo and 3dmark05 tells me that my pci express slot is version 1.0. I know it's supposed to be backwards compatible, but I don't want to order the card from newegg ,then it not work and be out all that money. I have a oem system so upgrading the mobo is out. I have already installed a 700w psu. I have seen some people say it works and some say it won't is there no definative answer? I don't like to leave my money up to chance. Thanks for your help in advance.

yes, it will work just fine.

I have a PCI-e 2 card running in a PCI-e 1 slot, it works just fine!

Cool thanks for the info. I'm going to move all my componets out of my hp case and into a bigger one to help with the heat problems ,I keep reading about, with the 8800gt.

PCI-E x1 or PCI-E x16? (Is PCI-E 1 = PCI-E x16?)

Umm... I'm talking about pci-e x16. For the video card my x16 slot is version 1.0, and I want to use a x16 version 2.0 card. I guess thats what your askin.
