the same by my two 4850 1 GB crossfire, both gpu´s are only 30%-46% working load ! cpu is phenom x4 940@ 3,6Ghz / 4GB RAM / vista64

i have round about the same performance(fps) how @MadDogX with this system: phenom x4 940 @ 3,7Ghz 2 x ati 3870 crossfire /cat 9.6 beta OC 4 GB DDR2-800 vista64 and this settings: 1920 x 1080 24" 3500m 100% all @ "high" only PP is "low" with shortcut -winxp

juhu you are a held! i have the same problem and your solution works fine!!:)

@ubascouser it´s differend from cpu to cpu, yes the 3,8Ghz / 1,5Vcore are stable by (prime) load 55° celsius, but i have the best cpu air cooler (IFX-14 with two 120mm fan´s) and the headspreder from the cpu plan grinded with arctic cooling MX-2 thermal paste! until 3920Mhz booted vista64 already but is not stable and to much temperatur with aircoooling. with watercooling system is it possible to get 3,8Ghz - 4,1Ghz with a very good cpu. now regarding arma2 and the summer temperatures, i clocked down the cpu to 3,6Ghz / 1,42Vcore by load 52° celsius (max. speci. temp from amd for phenomII is 62°) so the temperature are importend think regarding overclocking! but i think with a medium air cooling system, you can get 3,5 - 3,6Ghz without any problems. (but i think it is to close to the 62° max. temp, maybe 58°-60°) all over this 3,5 - 3,6Ghz is depending from the whole system configuration and productions qualitiy cpu , and the operating system.

cool:) the ati catalyst 9.5 is already running on my system without problems. thanks!

Hello all, what are you thinking about my system regarding arma2 with my 24"? i know the ATI 3870 CF is a little bit older.
