|Is your motherboard a separate purchase or part of a custom rig, OR is it from a manufactured system (HP,Dell,Gateway)? Or possibly a store brand? If this machine is a manufactured system, or a system made for a store, your BIOS will not have the options to overclock it. If so then you are out of luck as far as OC'ing is concerned. IF you can fit a decent graphics card, you have the power supply to power it, you still may achieve reasonable gaming performance at slightly lower settings, but much better than you have now.|
If not then save up to get or build a true gaming machine.
You have to be a little bit crazy to keep you from going insane.
