You shouldn't have to Optimise Ps or Br settings to get them to work reliably. You might want to optimise them to get the last ounce of performance from them.
I suspect something in your hardware or OS isn't 100% 64bit clean. We had these issues going from 16 to 32 bit. Until you have a proven 100% 64bit clean system, it will cause grief. I don't think it's just down to RAM, Ps and Bridge will swap out virtual ram by the wagon load all on their own.
A large, fast, dedicated HD for a scratch disk is a good idea, NOT the HD with the OS on it or that might even slow things down. Say a WD Black 250Gb would make a good scratch drive. If you plan to use an external it needs to be Firewire or eSATA. With a PC it's so easy to slip another internal drive in connected to the SATA bus. If you use USB for a scratch drive that could make things worse, it's so slow.
My figures for external drives:
USB drive Write 38MB/Sec - Read 39Mb/Sec.
FW drive Write 64MB/Sec - Read 78Mb/Sec.
FW RAID Write 64MB/Sec - Read 82Mb/Sec. (May vary depending on file type.)
I suspect the RAID is limited by the FW Interface.
Probably best to keep plodding away with 32 Bit until you are ready to upgrade the box, by then they may be cleaner and more reliable. I don't believe you need 24Gb for images, my i7 with 8 gig is unstoppable.
Even my little dual processor with 4Gb ram allowed me to open 1,750 D200 NEF's all at once, with ACR, the performance was not any slower than it would be for 10 NEF images. It did take a while to save all the JPEG's though...
Maybe video would benefit from more RAM because it's dynamic.
