You'd be far better off going with a quad core processor and a better graphics card. You also don't need anywhere CLOSE to 650w - a 500w unit will be plenty.
yea the budget is like 700$ so I can't go too hard on the graphics card. But ill look into it.
Like I said, you're better off cutting elsewhere. This is a _gaming_ computer - the most importing thing is the graphics card, and a 650ti was made to display slideshows, not games.
