ati xfire technology question.

my current mobo is
GA-EP45T-DS3R
can an nvidia 8800GT still work in it?
im just asking because the mobo says that it conforms to the pcie 2.0
as well as having ati crossfire technology,
i guess nvidia cards cant support the crossfire tech ( i have no idea on that one)
but does that mean the 8800GT will have issues on this mobo?

im only asking because i myself am having issues!
random freezes from bios - post - windows
maybe an issue with the graphics card?
