I know i need a new CPU, but it is not in my budget yet so i want to see how far i can SAFELY OC my current rig without damaging it. I have stock CPU cooler still and am saving money for an i5 ( since an i7 is out of my reach right now). I also know i am short on power ( 500 watt currently by thermaltake). Any one have any advice on a safe OC? Honestly i dont game too much but when i want to i want it to be smooth and look great. Currently my only game im having issues with is need for speed rivals. I can run on High settings with all bling but once in a while itll freeze for a second then back to greatness. Im definantly running a budget machine and trying to keep it that way but dont want it to perform like its on a budget. Any help would be greatly appreciated! thaks in advance
