suddenly out of memeory in The Win7 OS Forum Posted November 11, 2011 All I can say is that I have used the bcdedit switch on my Vista 32 bit system for years without problem. And I do video editing on this system, also.The OP has a nice system. It won't help with OOM, but I think his computer would benefit from the low prices on better GPUs. I have run an 8800gt (pretty much the same as your 9800gt) and my current GTX 260. Subtle, but there is improvement. And you can get much more GPU now for much less than I paid for mine.While a 64 bit system may be the best way to go, it is not the only way.Just a small suggestion...FS....FSX or FS2004, will work just fine even on 7600GT series cards, or ATI X1800...even older one will work just fine with FS. In FS, it's not problem in GPU, CPU is one that counts.With 16GB of memory, and, for example GTX590 the world best graphic card, but with some old dual core processor, you can be happy if you can run FSX on LOW settings with 15fps max.
