If you can swing two SSD's you sure won't be sorry. I'm using one regular drive for the OS, program files and X86 programs and a 10,000rpm Velociraptor for FSX. Makes my eyes bleed things look so good.

This is probably a data entry error. If you look on the same site you will see that the Acceleration addon package is 64-bit compatible. How could that be if the base package was not compatible?

Thats a very good point!

It does matter. On a 64-bit OS the video card gets its own separate address space, leaving more address space available to 32-bit applications than they would get on a 32-bit OS. This is in fact the main reason why running FSX on 64-bit Windows is a good idea.

See, this is why i love this forums, cause i learn something new every day from the knowledge shared in here!

FSX will not run any better in C:\FSX, it is just that if you install to the default location you *may* run into problems with certain addons because of the special protection Vista and Windows 7 gives to the default location. (If you do decide to use the default, don't change it to any language-specific folders - just use the default).

Okay, then I`ll be better off installing FSX on a different drive then that which contains the OS. Thank you for taking ur time! I truly appreciate it, especially when Im trying to aviod as much problems and bugs as i possibly canpre-new computer-new fsx-new addons-big time problems-era again:)

I note that DCS A-10c is available as both 32-bit and 64-bit native applications, with the developers recommending the 64-bit version as having better functionality. Let's hope MS Flight is the same. It's time MS came out of the stone age; but if MS use the same codebase as FSX I guess we'll be out of luck. Cheers,Noel.
