Good afternoon!

So I'm kind of in between projects right now so I thought it'd be an ideal time to perhaps try to squeeze some extra performance out of my processor by overclocking it. Before I go through the steps and tinkering with my setup, I wanted to see if anyone could gauge how much more performance (FPS with the same settings etc.) I'd be getting.

Currently I fly the PMDG 777, with payware scenery, customized WOAI traffic on 100%, frames locked at 20, and I see about 20 while I'm cruising and around 10 on the ground (when the AI slows it down considerably). My specs are:
Windows 7, 64bit
AMD FT(x)-4100 Quad core processor running at the stock 3.6Ghz
8.00Gb of RAM (I never really have memory problems)
AMD Radeon HD 6670, 1Gb of DDR3 Memory
(Hopefully I didn't forget anything important)

I've read it's not too risky/difficult to push my CPU up to 4.0Ghz or even 4.2Ghz. If I do, what kind of performance increase do you think I'll experience? I was thinking/hoping for just an additional 5 to 10 FPS without me changing any scenery settings.

Thanks in advanced for your feedback, I really appreciate it!

I think it's going to be difficult for anyone to exactly quantify your expected results but it seems a 25% increase in clock speed (to 4.5Ghz) isn't uncommon for your CPU so you could hope for an equivalent increase in frame rates within FSX (from 20 to 25). Obviously a half decent aftermarket CPU cooler will help achieve the best results with your overclock and therefore maximise the benefits to FSX.

I'm not as familiar with AMD as I used to be but hitting 4.0 with a good cooler maybe 4.2 sounds reasonable. Which may give you another 5fps. But I would also dial back the scenery a little, so that you are closer to 30fps when flying and 20 at the airport with heavy AI.
