Other than hardware supported video and graphics, I recommend setting powersave governor and decreasing max frequency. You can use the cpufreq extension to do this. If it is not supported then use cpupower. Even if you set max freq to 2 GHz, the system will be still as snappy and you will not loose anything in performance unless you are gaming.
