Fairly balanced if a build ?
Would not the effect of the "bottleneck" ?
Enough bottle neck if I will overtake, it is not very painful.
Not too "kosher" 32 gig ?
If the plans include a fresh gaming titles, then it is. Although it may be sufficient and 16.
Enough 500 Wat for this build, + 1 SDD+2 HDD WD 4TB.
Enough, but better to be safe and take the 650. Though only one GTX 970 consumption of power up to 500 watts, in practice it is impossible to replicate at home.
Me only interested in one thing: why make such an Assembly of the known old hardware store
? AM3+ is more dead than alive, nothing new on it, and never will. This is easier to buy with it. You're just a fan of AMD? Or gain the necessary critical mass for the purchase?
Just for the future it is better to wait for either Zen or to take something from Intel LGA1151. The same Core i3-6100, despite only two physical cores, very good comes to modern gaming titles even in conjunction with the GTX 980 Ti.
