i got the dfi 790fx m2rs board coming. i won't have the quad core for it yet since i'm holding out for better bins . anyhow, i will be experimenting with crossfire on this board. anything i should be aware of with working on it? i will probably be running with a 5000+ BE am2 proc. is there a thread with bios settings? this will be my first time venturing into an amd chipset. thank you very much.
