Just tried overclocking my E6750 and 3.2Ghz seems to be giving me a 5-6fps gain. It doesn't sound much but 16fps vs 22fps makes a big difference in gameplay. Unfortunately, the fan noise in idle is too high. Buying a good cooler isn't an option as it would cost more than my CPU is worth. If I were to go over my budget, which processor would you say does have a good price/performance ratio for ARMA 2 right now?
