Will it get good results? I've recently purchased a pre-made custom rig, and it contains an a8 3850 apu. I'm on a budget so it seemed like the best choice for the moment. I'm wondering though, if I may be able to upgrade the gpu (disabling the onboard gpu) some time in the future and keep up with the times? Or will I have to get rid of the a8 completely and start fresh with a new cpu and gpu?
