Since the 790FX-based DFI board in sig rig isn't completely happy with my Phenom II X6, I've been wanting a new board and was thinking a 890FX board would be the best bet between compatibility, features, overclockability and cost. Budget shouldn't be anything, but I could spare $100-ish. Going on the "Old tech should be cheap now" theory, my first instinct is the ASUS Crosshair IV and it turns out there are some relatively inexpensive Extremes out there listed as "New (See Other)", which details show means "board only, no accessories". Besides the lack of backplate ($20?!), this seems like a good option. I haven't really seen much more than that, so it's either this or an AM3+ board which I've heard doesn't do voltages nicely with AM3 processors. Thoughts people?
