Yes it's worth it and is the reason I skipped it and went with the FX 8350. I wasn't about to make the same mistake I did when buying the FX 6100. Don't get me wrong the 8320 is a nice cpu but I want the most OC headroom possible and I got it. Even at stock speeds with the turbo it's a beast, I'm at 4.8 right now with OC. I run BF3 at Ultra settings with NO AA with advaptive vsync on and cards in SLI with three monitors at 6080x1080p. My cpu is never goes above 45% use, everything is put on my video cards.
Well im not overclocking much and it will be first time overclocking so no going crazy
