I plan to buy a GX2 at some stage and just wanted an interim fix really. Would a 3870 and an NVidia be problematic in the same machine?

Hmmm, so i am trying a 3450 with the 3870 and its just crashing.. i think the intel 975xbx drops both PCIe to x8 with two card installed and that card requires x16 - or so it says on the box. Anyone have a solution to this.. would xfire-ing them help solve this?

Yes they need to be crossfired, then set your display options however you want using CCC.
