I'm seriously thinking of trashing the Phenom chip in this computer. I have FSX DE and want to run it, but I have read in these pages that four-cores are not compatible with it. Would I suffer such a frame hit if I went the two-core route?

And that's another question: When I set "Target Frame Rate " in Settings, is that what I hope the machine will achieve if it can, or what it will give me based on what kind of horsepower is in the chip, RAM and video card? I have it set 47 or somewhere near that now. Suppose I set it at 99. Would I get it? If I set it at 15, would I get that? I'm so confused...

As I understand it should just ignore any cores not being used. more cores is better! you don't always fly on the computer do you? as for the target frame rate, that is what you are demanding the sim achieve so the higher the number the harder it has to work the whole system to get that and try to stay there,  in addition to everything else your system is doing at the time, The eye can't really tell the difference past 25fps, so for that reason I keep mine locked at 20, and it stays there nice and steady. I like to keep the scenery pretty dense and detailed with lots of traffic, so I could probably go higher with less goodies around, but the action stays smooth enough for me at 20.
Hope this helps!

OK. Thank you, SG. I think I'll just leave it at 47. That's 1.5X faster then the eye can see, so it should provide better than true-to-life smoothness in the playback. I might drop it down to 40 to get more sources directed to the sim over the scenery. I run everything at or near max (I like lots o' clouds) and I don't seem to see much stuttering...
