What can I upgrade to increase frame-rate for MS FSX (flight simulator)? When running FSX, I can’t get the frame-rate over 20 with all the sliders set past 75%. I’m running the resolution at a maximum of 2560 X 1600. My goal is to do whatever I can to increase frame-rate. The CPU temperature runs between 68 and 90 degrees during game play.
I’ve considered adding memory, changing video cards and/or changing the processor to i7. I’ve also considered a different cooling solution, but don’t know where to start. I would appreciate any suggestions.

Existing system:
Asus Maximus Extreme motherboard.
4 x 1 GB (4 GB) OCZ Titanium 240-pin DDR3 SDRAM1600 Dual Channel memory.
An Intel Core 2 Q6700 Kentsfield 2.66 GHz 2 x 4 MB L2 Cache LGA 775 Processor.
Two Diamond Viper ATI Radeon HD 2900 XT PCIE 1GB GDDR4 Video Cards running in Crossfire mode.
Asus Arctic Square CPU Cooler and an auxiliary fan.

Memory is fine. You could most likely get away with replacing the graphics cards with 2 ATI 4850 or 4870's to increase the frame right. Alos, 467x series are going quite cheap right now, so 2 of those would also provide you with increased frame rates. Your CPU temp hits around 90? That seems a bit high...

I agree with Memory

if you are running a 32 bit OS don't waste your time or money on Memory
