So what is your PSU? The HD 4770 consumes about 50w during gaming, the HD 5770 consumes about 61w while gaming. Running something like FurMark will push the HD 5770 to around 81w. Don't know about the HD 4770.

Do not bold.

The system is fine but yeah, depends on the PSU. If it's 450W or more then yes.
