My friend is looking to upgrade. He currently has an i7 870 overclocked to 3.8GHz. He's looking at an FX 8320 which he hopes to clock to 4.4-4.6GHz with a H100. He has SLI GTX 660 Ti's and games on a 60" 1080p HDTV. Will the FX 8320 give a noticeable boost in performance? I tried googling for benchmarks but most don't compare the older i7 to the FX processors. So I couldn't really get an idea of how they compare. Also, his i7 870 is at its max for overclock. So don't suggest just overclocking that further. He bought the H100 in hopes of pushing the i7 further but it just isn't stable past 3.8GHz. No matter how high he sets the voltage it will not go any higher. I think his board is actually the limiting factor here. So since he has to replace the motherboard anyway he wants to upgrade to a more modern CPU at the same time. And good socket 1156 motherboards are impossible to find new.
