Everybody, thanks for replies! I checked my mobo cpu support list and.... it does not suport fx cpu's T_T... like at all. So my plan to upgrade just cpu from 4 cores to 6 fx cores failed miserably. I think....*sigh* I will wait for that new "zen" cpu looks like it will be released quite "soon". Maybe will get used fx + used mobo cheaper. I'm quite poor person to be honest. Anyway... I still can enjoys sl just will need to wait more to get better experience.
