ya, I'm fine with using only pcie x4 bandwidth but I only have two full size pcie x16 size slots. one being x16 and the other x8. If I am unable to do what I need, I may have to end up upgrading which is something I don't mind but the wife will. I'll see if I can find anything that can take one x8 and made it two x4 or the x16 and make four x4 or two x8. I think I'm up a creek though.
