Exactly what aspect of your performance are you trying to improve?
If it is fps for gaming, upgrade the graphics card.
If it is for a cpu bound multithreaded app like rendering, replace the cpu.
If you just want general quicknedd, buy a SSD for the os and some apps.
Well that’s the thing… I’m not trying to accomplish any one particular thing. My goal is to max out and then OC my PC for no better reason than to learn how to do it. So far I have watched a lot of videos and read a lot of forums, now I want to actually start working on the hardware. Due to a severe lack of disposal income, I need to do this without destroying my stuff. I’m not looking for detailed schematics, just some pointers so I don’t go down the old trial and error road.
