So in anticipation of Bulldozer and me wanting SLI, I was wondering whether I should upgrade my motherboard to a 990FX AMD board? I probably won't get a Bulldozer CPU right when they come out but I'd like to have it so if I do upgrade eventually plus the board supports SLI, my current is Crossfire only. Would it be worth it to upgrade? I've been looking at the ASUS Sabertooth.
