A friend recommend this video card is it good for gaming?
Its good for gaming, but I can not vouch for the GPU retailer PowerColor. I have never really heard and/or used any of their cards before, so I would recommend researching and asking your friend if he has had any bad experiences with this particular retailer. As for the rest of your build it all seems pretty solid. I do want to point out that your CPU is not unlocked if what I have been told is correct and can not be overclocked.
