I have a trifire 5970/5870 @900/1200 system on GB UD5 4ghz i7920
I notice stuttering in Arma 2, I use onboard sound but also my memory is at 1200 mhz 20 8 8 8 1T (it's a barebones preoverclocked system). Memory was at 29 9 9 9 2T (I guess for simplicity and the magic 4gz number overclockers UK ust slacken off memory timings.

How do I get rid of stuttering -faster memory? OR a sound card to off load CPU. Windows 7 64 bit

Or are both a waste of money?
