Computer Newb here. Just got Battlefield 3 and want to upgrade my graphics card for better game play. My specs are:
Dell Studio XPS435T with i7-940 processor 2.93 ghz
8GB DDR3 Ram @ 1066 MHz
512MB Radeon HD4850
Power Supply is 425W (Not sure what make).
I want to upgrade to 1GB HD6950. I think the processor will handle it, but can I just get the new card and plug it in? Never opened a computer before and am not sure of the power pin connector types. Does anyone know if this will work, or will I need a new PSU?
