If you're running AMD system you want to keep temps on the CPU core under 50C at all times. This can be achieved with an after market cooling solution like the Cooler Master Hyper 212 EVO.
Your GPU temps are fine unless you get to a point to where they begin to exceed 60-70C...then you need to worry.
I would recommend ensuring your case has at least a few large fans exhausting air from inside, as things tend to get hot in a poorly ventilated case. So for the cost of a $10 case fan and a $25-30 CPU fan, you can get your temps down to a much cooler window inside your case and inside your CPU.
