you can get the phenomII x6 for the same price new: AMD Phenom II X4 960T ~104€ you can unlock this cpu to an x6.
but i think your price for the mainboard is to low i don't find any good mainboard for this price.
for amd you need at minimum 65€ for a "AMD 970/SB950 " chipset based mainboard.
a FM1 amd mainboard is cheaper (with all features) :

and you get a quatcore + Radeon HD 6530D
http://geizhals.at/de/653207 for 76,99€ a FM1 system also can handle 32gb ram.
i think for your low bugged a AMD A-Series A6-3650 system is the best solution.
