Am3+ combo

Got a 3 week old LNIB M599X EVO 2.0 along with FX 6300 and 2x4gig kingston hyper x black 1600 mhz ram.  Whats a fair price for this combo?

New that would be around $340 if I am not mistaken.
I would say sub $300 would be fair.

I have a few amd combos to some sold fast some not so fast.
