Expert Advice On A New Rig Please

I am planning to build a new PC entirely for running FSX maxed out and with a good frame rate. I already bought the following components and plan to use Windows Vista 32 bit.Processor: Intel Q 9550.MB: Asus P5E (X38 based)RAM: 4GB of Kingston HyperX DDR2 800MHzGraphic processor: XFX Geforce 8800 GTS 512 mb XXX Edn My questions are1. Will the above components be good enough to achieve the goal?2. Is there any advantage in having a RAID 0 setup with two Seagate 7200RPM SATA2 32MB Cache hard disks?3. Will the hard disks with 32 MB cache offer any extra advantage over 16 MB with regard to FSX?I would very much appreciate an expert advice. Thanks in advance.Vinod.
