I have this system setup:- AMD 64x2 4000+ (finally I'm back with this system I had to leave behind 3 years ago).- ATI Radeon HD4350 (for replacing an old AGP card I had installed)- 2x 1GB RAM DDR2I've just bought a new motherboard so that I could replace my old AGP GPU (an elderly Geforce FX5500) with the Radeon. Almost everyone recommends a reformat when changing motherboards, so that would be a chance to try Windows 7 in this system. Is it worthwhile? Or should I stick with XP? In any case, I'll keep using 32-bit versions, and I'll be running FS2004 on it.Best regards from Colombia,Luis Miguel

Hi Luis.I think only amount of memory is a potential problem for W7.I switched from XP64 to W7 64 bit and I will never go back.FS9 works ok but remember to turn off UAC , install as admin on non default location.Because of memory I suggest you to stay with XPMy opinionEdin

Ram is cheap.I suggest you get more.

Nothing wrong with XP, If that's what you like. I must say that I have ME, XP, Vista,Linux, and W7 running at my house. W7 64 bit is slick and fast. FS may not run faster, but everything else will. Bob

Well, I just decided to install 7, it's just more "brotherproof" than XP :( (I hope my brothers don't read this). FS9 runs very smooth, it only complains when there is overcast sky (and with 1024x1024 Pablo Díaz' clouds), but I don't know if it's because of 7 or my video card.Anyway, thanks to everyone.Best regards from Colombia,Luis Miguel

I don't think you will get any performance improvement with FS9 using Win7 and you may have some problems. I suggest you stick with XP - that's the system Fs9 was designed for. I am using Win7 because my system came with it but if I had to do a reinstall (G-d forbid!) I would probably ditch Win7 and get XP Pro...

If I were you, I would stay on XP x86.A few months ago I migrated from XP x86 to Win7 X64 because of hardware changes and driver issues.Although FS9 runs pretty good on W7 my feeling/believe is that it runs better/smoother under XP.You have 2GB of RAM, so you won't benefit much from Win7 anyway

FS9 is a 32 bit program. XPpro is fine. Better the devil you know than the devil you don't. Using W7 provides you with headaches because you don't know how to deal with the things that you breezed within 'XP'.

HelloRun it on XP64 bit if you can.Totally compatible with FS9 and you get the benefits of 64bit with the familiar and much better interface of XP.Patch FS9 to be Large Address Aware and you have a really solid platform with zero OOM issues.
