Is overclocking going to make much difference to my fps on FSX?

I'm new to the world of pc gaming, but I needed a good system to run fsx on without breaking the bank. at the moment, I run fsx on this system:
AMD Phenom II X6 1045t 2.7ghz
ATI Radeon HD 5770 1gb GDDR5
8gb ram
1tb hard drive
Windows 7 home premium
(resolution: 1360x768)

i get around 25-50fps depending on the weather and the aircraft, and the settings aren't all maxed out.
is there any point in overclocking? or could someone suggest optimum settings which give smooth flight and the best graphics possible? thanks

You very well may gain a few FPS by OC'ing. FSX is one of those odd games that is extremely CPU dependent (don't ask me why) :rolleyes: FSX is usually fairly fluid @ 25 FPS, so if you OC your PII x6 up to 3.7Ghz , you may be able to get the next level of settings.
