Okay I want to upgrade my pc so i can play games like bf3 bf4 on med-high settings. I have a dell inspiron 530 pc with intel core quad q8200 2.33 ghz cpu and 6gb ram and ati radeon hd 4600 . I want to buy either a new cpu or graphics card. I want to know what my computer will use. I don't want to spend more than $100 for each item. Also I think i have a 350W dc output and input 100-127V~/10a power supply. so I need help deciding what to buy a cpu or graphics card.
