I am looking into building a gaming machine with a budget of $700. I have decided to go with a socket am2+ motherboard, so that i can upgrade to a phenom processor in the future. I will start out with an athlon 64 x2 between 5000 and 6000, depending on how much i have left after the graphics card and the motherboard, about a gig of memory and all. My question is what is the best type of motherboard to go for that fits these specs? I am leaning towards a radeon hd 3870 graphics card. Because of this, it is necessary that the motherboard has crossfire support. So all in all, I am trying to find a quality socket am2+ motherboard with crossfire support under around $200. I have looked around and it seems that the possibilities are endless. any suggestions would be greatly appreciated.
