I'm a bit of a noob when it comes to computer hardware, I have an HP Pavilion p7-1234 with a AMD A6-3650 APU that is 2.6 GHz and was wondering if I could put in a GTX 650 ti Boost in it. I've read that this can bottleneck your processor but is there a way to stop the graphics in the APU and just have it be a CPU. I do not want to spend the extra money on a new CPU if it isn't totally necessary. Thanks!
