Lag problem please help !!!!

[antoinersca]

I just bought a new computer GTX 680 and an Intel I7 2700k overclocked at 4,5 Ghz.
Even with that rig I have a lot of lags during my flights. I use a lot of addons but a computer like that  must running all that stuff without flags !
Can someone help me ? Can you give me some tips ? 
Thanks

First off make sure you have configured your FSX.cfg correctly
The Addon Manager does a good job but you can also use this great website

What RAM do you have?
What O/S are you running?
