I have a MSI 790fx-gd70 running SLI right now (even though its a crossfire board) by using a software SLI(x58) hack, however the newer nvidia drivers do not work with this method and are not stable. I have tried the search function to locate if any modded bios are available that would make my MB appear to be sli capable at the bios level and have not had much luck. If anyone could point me in the right direction or let me know if this exists/is possible I would greatly appreciate it. Thanks.
