I am looking at mATX dual PCIe 16x boards for AMD (either DFI Lanparty JR of the new MSI 890GXM) and wondering if they are worth it over a normal single 16x board. Basicaly it comes down to dual GPU usage options.
What is the current state of crossfire usability in Linux ? Does it make sense to purchase such a mobo now (or say a year timeframe from now)?
I have seen some ancient tests when crossfire was introduced, but since then I saw nothing usable for my situation.
