Your case is overpriced, the Antec 300 offers the same thing but cheaper.
That hdd is to slow for games, the Spinpoint 300 is waaay faster.
Your mobo is overpriced also, the GIGABYTE one is a better value and offers essentially the same thing.
Your gpu is simply to weak for the budget, that thing is for $500 budget systems and below.
That psu could potentially die on you and take your pc down with it. The one I choose is a good brand and offers more power at a lower price.
That ram does'nt need to be that expensive. Ram simply doesn't make that big of a difference in a gaming machine compared to the cpu/gpu.
Finally your processor is underpowered for your budget.
But all in all good shot though!
