DeathRabit :
Good quality mobo, poor quality PSU * (but you can use it, for this build)
What rams you have ? * this CPU like have 2133Mhz/CL9.
What cpu cooler you have ?
Because it is time for OC your CPU and adjust rams
If cpu usage is at 50 - 60% then overclocking will not help a great deal .
The OP mentions frame rates but not the resolution of his monitor .
OP what screen are you using?
What operating system are you using? Is it 32 bit , or 64 bit?
Have you checked in task manager to see what else is running at the same time and how much RAM it is using ?
