Primarily for gaming, watching HD movies on the 52 inch LED which is also going to be the monitor. Ill be playing GTA 5, Assassins Creed, Counter STrike, HL 2, Sims 3 plus expansions and other fun games in the future.
As for not picking intel, I am not paying 120 more for the i5 to have almost the same stats. I went to the graphics section on this site and the 4100 did well, almost as well as the i5.
For the mobo, if it is actually better, ill get that but please give facts to back up the claim. Thanks
