Brett:
Sorry, you are right it appears. i checked online for the gateway specs and it tells it is 64 bit!! I wonder why when I check my system, it says 32!!!????? Wild..... anyway.. the graphics is onboard and sounds weak.... 224 mb ram... I cant upgrade at this time, so I will go for 2004 for now and in a year or two.. if they dont have a good Flight simulator game for Playstation 3... I'll upgrade! ;-)
You are probably running the 32 bit version of windows. But the processor was built on the 64bit architecture. processors have been built that way for a while now.
My guess is you could run FS 2004 with no problem, but FSX would run slow or you would need to lower the resolution a lot to get it to run at playable framerates.
