hi again,because i want to get a new system in the next week, i would like to know your experiences with dual core processors. i know that fs9 is not providing dual core at the moment, but will i have the full power (for example athlon 3800+) of both cores or will only one work so tha t i will only have about 2ghz available for fs? or will they provide full power of 3800ghz if i need them in high etailed sceneries with pmdg747 for example? i didn`t find any thread that gives me a clear answear to this... so, if anyone uses the athlon x2 3800+ and a similar gpu(msi 7800gt, 256mb), could you please post how many fps you get with high scenery, aircraft, weather and traffic?thx again and regardsphil

You got a the answer in your other post FS9 does not use dual core, you will only be using one of the two cores when gaming, also search the forums, this has been talked about a lot!

Yep, FS9 does not use Dual core. Looks like FSX will though!

My guess is that, even though the program code of FS isn't designed to split tasks between the processor cores, the operating system is going to know that when you're running multiple programs along with FS, to span those apps across the dual architecture. What this will mean to your FS experience is that you can run FS full bore and not see any degradation while surfing the internet, doing graphics work, etc. For that functionality you don't need to wait for FSX.Art

Don't know what that means "does not use dual core" - but AFAIK, and I am no engineer, it's not FS9 that counts, its the operating systems ability to assign tasks. Windows XP does that - albeit not 64 bit. I use a PentiumD 2,8 GHz (the "920") and when I run FS normal it uses both cores. When I use the task manager to limit its affinity to one CPU, performance drops, so it definitely makes use of both CPUs. If you are deciding between dual core or a high-end single core system like the Athlon60 - I think the biggest decision factor is the way you use your computer. I do a million OTHER things while flying, especially long-haul flights :). With my dual core system, I can burn a CD, copy files, build a flight plan, surf the internet, all while flying VHHH-EGLL in my PMDG 747, and there is absolutely no slow-down effect. If you do not multitask like me, then a single-core may be a better choice.
