Don't follow you, why does $99 at microcenter make you want to sell yours?
i paid 135$ for the FX 6300 after shipping. It has 6 cores. They offer the better CPU (FX 8320) which has 8 cores (an extra module) for 99.99...its normally like 150$. I sold the FX 6300 for about 85$.
I also do 3D modelling and eventually some animation so the extra "cores" goes a long way with renders. Also its better for a lot of games, granted the lower single core performance i deal with now puts my frames a tad lower, but thats generally older games that arent highly threaded.
