I just got a new laptop, specifically an Inspiron 17 5755 with 12 gigs or ram, a 2 terabit hard drive, and AMD A8 with Radeon R5 Graphics. Everything about the computer is great so far, but the processor with built in graphics cant handle gaming. On Fallout 4 on extremely low settings i can only get about 15 FPS (unplayable). Could I order a factory Fx 8800p with R7 graphics directly from AMD to replace mine since they have the same socket style (FP4)? And if I can how would I go about doing so?
