Well I took everyone's advice and Id like to say "Thanks to Everyone". I replaced vista 64 with Windows 7 64, wiped everything out and reformatted and MAN what a difference. Im not saying the windows 7 did the trick on better frames for FSX, I think it was a combination of that and all the JUNK that I had accumulated over the last few years in FSX. I am steady at 25 fps with most of the sliders to the right. I spent all night and most of today re-installing GEX usa, GEx Europe, Ult terrain USA,CAN and EUROPE and Alaska and finally installing Tongass X about an hour ago. I stll need to Defrag but if the fps Im getting now are any indication it should be a smooth ride. I almost forgot I also installed REX2.0. I put most of what I could on drive c and pretty much only dedicated stuff to drive D wich is where I have FSX. I was considering just getting the whole ddr3 I7 processor and a new mother board, but after my initial run with my current setup I am very pleased. So thanks to all that gave me the advice, you saved me alot of money. My current setup is Q9650 Oc'd to 4.0 and 4 gig of ddr 2 ram with an 8800gtx on an asus motherboard. In short take a look at what you have stashed in fsx and clean it out if you dont use it becouse I think that had alot to do with my performace upgrade in the area of FPS. Just my opinion.
