Ok thanks. i tweaked it a bit so now i can play on 50-60 fps on medium and high quality settings mixed in. Lets say i would like to upgrade parts on on my computer. What part would need to be changed in order to make my computer more powefull for gaming?
I would suggest getting someone who is knowledable with computers to help you out. You can also read articles and Youtube tutorials to take out the old cpu. For price that would be another thing you would have to research. Prices do change on a daily basis. http://pcpartpicker.com/part/amd-cpu-fd6300wmhkbox
The Clock Speed of the CPU is measured in Hertz or Hz (1 oscillation per second), however using Hz means you would have a ridiculously large number, so Megahertz (Mhz) or Gigahertz (Ghz) is used to shorten it (1000Mhz = 1Ghz). The faster the clock speed, in general the more performance you get because the CPU is running faster.
However the assumption of a greater speed meaning more performance only works when its the same CPU being tested. For instance, you cant compare an AMD chip against an Intel using the Clock Speed, because they are different CPU's. The amount of cores also matters as well, so you cant compare an Ivy i3 against an Ivy i7, because the i7 has double the amount of cores and will outperform the i3 despite the similar clock speeds.
The best example of where it does work would be the FX-8320 and 8350. Both are the exact same CPU, except the 8320 is clocked slower. If you overclocked to an 8350's speed, they would perform identically.
