Hello there, I am looking to upgrade my old 2014 computer this Christmas, I am planning on buying a EVGA GeForce GTX 960 4GB SC GAMING, Only 6.8 inches the reason I chose the small one was because my computer motherboard is small motherboard for AMD Processors and I do not think it will fit, So I have done my research about the graphics card now I am on to the Cpu, Currently in that computer I am upgrading I have a AMD A6-5200 and I am wondering do I need to upgrade the Cpu also? Like to a Amd Fx-6300, I just want something that wont bottleneck my GTX 960
