FSX

I used Wideview FS but still want to run FSX on a single PC to have realistic
another traffic or "easy to run" environment.
Let me write down current hardware configuration bellow first.
Core2Duo E6700 2.66GHz
Asus P5N32E-SLI
HDD RAID striping
2GB DDR2-800 5-5-5
4GB DDR2-800 5-5-5(GX24GB6400DC)
Win Vista Home 64bit
LCDs
A) 5040 x 1050(TH2GO) for Cockpit View
B) 1650 x 1050 for Panel View
C) 1280 x 1024 for FMC

XFX GeForce8800GTX for A
Leadtek GeForce9800GT for B&C
FSX with FS Traffic. Test Flight at RJAA traffic pattern with default CRJ700.

As of today, system missing 4GB DDR2 due to hardware defect and I already sent them back to maker GeIL. Not known when they came back hence only the system is driving 2GB of DDR2 for now.
With the above environment, 6-8fps at ground and 4-7fps during the approach to the airport... How much I can get it from here? to be continued.
